To face the new challenges posed by the upcoming increases of the LHC proton beam energy and luminosity, a series of upgrades is planned for L1Calo. This paper presents the L1Calo upgrade program for the initial upgrade phase in 2013-‐14. The program includes substantial improvements to the analogue and digital signal processing to allow more sophisticated digital filters for energy and timing measurement, as well as compensate for pile-‐up and baseline shift effects. Two existing digital algorithm processor subsystems will receive substantial hardware and firmware upgrades to increase the real time data path bandwidth, allowing topological information to be transmitted and processed at level-‐1. An entirely new subsystem, the L1 topological processor, will receive real-‐time data from both the upgraded L1Calo and L1 muon trigger to perform trigger algorithms based on entire event topologies. The upgraded system presented is foreseen to operate for three years, after which a second, substantial upgrade phase is planned. The expected performance improvements are presented together with the upgraded hardware and firmware implementations. The status of the prototypes, integration and commissioning efforts are also reviewed.

It receives and buffers data of events accepted by the first-level trigger from all subdetectors and first-level trigger subsystems. Event data are subsequently forwarded to the High-Level Trigger system and Event Builder via a 1 GbE-based network. The ATLAS ROS is completely renewed in view of the demanding conditions ex pected during LHC Run 2 and Run 3, to replace obsolete technologies and space constraints require it to be compact. The new ROS will consist of roughly 100 Linux-based 2U high rack mounted server PCs, each equipped with 2 PCIe I/O cards and two four 10 GbE interfaces. The FPGA-based PCIe I/O cards, developed by the ALICE collaboration, will be configured with ATLAS-specific firmware, the so-called RobinNP firmware. They will provide the connectivity to about 2000 optical point-to-point links conveying the ATLAS event data. This dense configuration provides an excellent test bench for studying I/O efficiency and challenges in current COTS PC architectures with non-uniform memory and I/O access paths. In this paper we will report on the requirements for Run 2 and on design choices for a system complying with and possibly exceeding them, as well as discuss the results of performance measurements for different computer architectures, highlighting the effects of non-uniform resource distributions. Finally we will present the status of the project and outlook for operation in 2015.

The ATLAS experiment at the LHC will be able to maximise the physics potential from this higher luminosity only if the detector, trigger and DAQ infrastructure are adapted to handle the sustained increase in particle production rates. In this paper the changes expected to be required to the ATLAS detectors and trigger system to fulfill the requirement for working in such high luminosity scenario are described. The increased number of interactions per bunch crossing will result in higher occupancy in the detectors and increased rates at each level of the trigger system. The trigger selection will improve the selectivity partly from increased granularity for the sub detectors and the consequent higher resolution. One of the largest challenges will be the provision of tracking information at the first trigger level, which should allow a large increase in the rejection power at this stage of the selection and yet still allow the full physics potential of the experiment to be fulfilled. In particular, the electroweak scale still requires to keep the thresholds on the transverse momenta of particles as low as possible and tracking will provide essential information that could be used to this aim as early as possible in the trigger chain. Studies to understand the feasibility of such a system have begun, and proceed in two directions: a fast readout for high granularity silicon detectors, and a fast pattern recognition algorithm to be applied just after the Front-End readout for specific sub detectors. Both existing, and novel technologies can offer solutions. The aim of these studies is to determine the parameter space to which this system must be adapted. The status of ongoing tests on specific hardware components crucial for this system to fully satisfy the ATLAS trigger requirements at very high luminosities and increase its potential are discussed.

Gabrielyan on behalf of the ATLAS Muon Collaboration The Level-1 (L1) trigger for muons with high transverse momentum (pT) in ATLAS is based on chambers with excellent time resolution, able to identify muons coming from a particular beam crossing. These trigger chambers also provide a fast pT-measurement of the muons, the accuracy of the measurement being limited by the moderate spatial resolution of the chambers along the deflecting direction of the magnetic field (eta-coordinate). The higher luminosity foreseen for Phase-II puts stringent limits on the L1 trigger rates, and a way to control these rates would be to improve the spatial resolution of the triggering system, drastically sharpening the turn-on curve of the L1 trigger. To do this, the precision tracking chambers (MDT) can be used in the L1 trigger, provided the corresponding trigger latency is increased as foreseen. The trigger rate reduction is accomplished by strongly decreasing the rate of triggers from muons with pT lower than a predefined threshold (typically 20 GeV), which would otherwise trigger the DAQ. We describe the architecture for reading out the MDT synchronously w.r.t. the relevant beam crossing and in a sufficiently fast way to fit into the available L1 latency. The adaption to chamber geometries in barrel and end-cap will also be discussed. We present results of a prototype test at the Gamma Irradiation Facility (GIF) at CERN as well as the performance of a demonstrator module, containing most of the required functionality. In addition, simulation results are shown which demonstrate the rejection efficiency for muons below a given pT-threshold, taking into account deteriorating effects like delta-rays, conversion background and tube inefficiencies. Summary The Level-1 (L1) trigger for muons with high transverse momentum (pT) in ATLAS is based on chambers with excellent time resolution (better than 20 ns), able to identify muons coming from a particular beam crossing. About 600 of these trigger chambers are located in the central region (eta<1) of ATLAS, while about 3600 are covering the forward region (1<eta<2.4). In the central and forward region the chamber technology is of the RPC and TGC type, respectively. A detailed description of the present ATLAS trigger scheme and chamber technologies is given in reference [1]. The trigger chambers also provide a fast pT-measurement of the muons, the accuracy of the measurement being limited by the moderate spatial resolution of the chambers along the deflecting direction of the magnetic field (eta-coordinate). The limited momentum resolution of the trigger chambers weakens the selectivity of the L1 trigger for high-pT muons above a predefined threshold, like 20 GeV, allowing muons below threshold to cause “fake” triggers, mostly corresponding to event signatures without physics interest. The higher luminosity foreseen for Phase-II puts stringent limits on the L1 trigger rates, and a way to control these rates would be to improve the spatial resolution of the triggering system, drastically sharpening the turn-on curve of the L1 trigger with respect to pT. This is possible due to the close matching between trigger and MDT precision chambers in the Muon spectrometer. The selectivity for high-pT tracks can thus be improved by combining the excellent spatial resolution of the MDT with the time resolution of the trigger chambers. In this concept, the trigger chambers will be used to define regions of Interest (RoI) inside which high-pT muon candidates have been identified. MDT hits in the RoI(s) are passed to the trigger logic, where they are used for an accurate estimate of the track momentum, leading to an efficient suppression of sub-threshold muon triggers. In order to collect the MDT hit coordinates early enough for use in the L1 trigger logic, the relevant hits are read out through a priority readout chain, independent of the standard, asynchronous readout. Considering only MDT hits inside the RoI(s) strongly reduces bandwidth requirements and latencies, in such a way that transfer and processing of the MDT for the L1 trigger decision can be accomplished within the 20 mysec L1 latency, available in Phase-II. We present the architecture of the MDT trigger system together with estimates of latency and spatial resolution as well as test results from a prototype, performed at the CERN Gamma Irradiation Facility (GIF) early this year. We also present results from a demonstrator module, containing all essential components of the readout system to be used in Phase-II. In addition, simulation results are shown which demonstrate the rejection efficiency for muons below a given pT-threshold, taking into account deteriorating effects like delta-rays, conversion background and tube inefficiencies.

See below a detailed summary of your submitted abstract: Conference: Tipp 2014 - Third International Conference on Technology and Instrumentation in Particle Physics Submitted by: SFORZA, Federico Submitted on: 29 January 2014 12:25 Title: Upgrade of the ATLAS muon spectrometer with the installation of new precision drift-tube chambers in 2014 Abstract content The shutdown of the Large Hadron Collider (LHC) at CERN in the years 2013 and 2014 offers the opportunity to improve the performance of the ATLAS muon spectrometer by installing additional muon tracking chambers. The additional chambers use a new technology with precision drift-tubes of half the diameter of the standard ATLAS monitored drift-tubes, thus allowing for a more compact geometry. This makes possible the addition of a third layer of precision muon tracking chambers in detector areas that are, at present, instrumented with two layers of chambers. The momentum resolution of 1 TeV muons reconstructed in the upgraded regions will improve from 28\% to 19\%, a value consistent with the rest of the muon spectrometer. The new chambers are designed for simple integration with the present service system, the read-out electronics and muon reconstruction software. In order to provide access to the inner part of the ATLAS detector, the new chambers will be mounted on a movable structure that can be aligned with the other chambers with 30 $\mu$m accuracy. Summary The shutdown of the Large Hadron Collider (LHC) at CERN, taking place in 2013-2014, offers the opportunity to improve the performance of the ATLAS detector with the installation of new detector components. However the relatively short time window and the constraints due to the integration of the new components with the existing infrastructure limits the range of available solutions. We present the upgrade of a section of the ATLAS muon tracker with drift-tube chambers characterized by a new technology, with smaller tube diameter than the present Monitored Drift-Tube (MDT) chambers. The proposed layout balances between maximizing the coverage with muon stations, the tight constraints of the integration with the present infrastructure, and the benefits of using the new stations for detector R & D. Each new chamber is composed by eight layers of 78 aluminum tubes with a diameter of 15 mm, against to the six layers of 30 mm aluminum tubes used in the corresponding ATLAS MDT chambers. A gold-plated tungsten-rhenium anode wire is tensed at the center of the tubes with a position precision better than 10 $\mu$m. The design remains fully compatible with the present services, read-out and trigger scheme but the more compact geometry of the chambers allows their installation in currently unequipped regions of the detector structure. The presence of additional tube layers increase the redundancy in the track reconstruction and allows for better noise rejection in the dense tracking environments expected for the future LHC run conditions. Two new chambers will be installed in the ATLAS detector elevator shaft. This region, covering an area of $\Delta \eta \times\Delta\phi\approx 0.2\times 0.3$ and corresponding to 1\% of the ATLAS barrel region, is used to access the inner part of the ATLAS detector and the ease of accessibility must be maintained. This additional challenge has been solved by installing the stations on movable supports and using an optical alignment system, designed to be precise at the level of 30 $\mu$m, integrated with the rest of the ATLAS muon spectrometer. The upgrade will increase the area of the muon spectrometer equipped with three layers of precision tracking chambers. This will improve the momentum resolution of the newly instrumented regions, for 1 TeV muons, from 28\% to 19\%, consistently with the rest of the ATLAS muon spectrometer. The installed chambers are also the first step of a larger upgrade of the muon spectrometer barrel region planned for the ATLAS Phase II upgrade.

It uses a new shielding concept by operating bare Ge diodes (enriched in Ge-76) in 64 m^3 of liquid argon supplemented by a 3m thick layer of water. The results of GERDA Phase I have been published recently [1]. Compared to previous Ge experiments, a background reduction of about one order of magnitude could be achieved yielding the so far best limit for 0v2b decay in Ge-76 and refuting a recent claim of discovery with high probability. The upgrade to GERDA Phase II is in progress; it strives for a further reduction of background by another order of magnitude towards a level of 10^-3 cts/(keV kg yr), and for a tenfold increase in half-life sensitivity (10^26 yr) at an exposure of 100 kg yr. This paper will discuss the numerous challenges to be met for reaching these goals including the increase of target mass by 20 kg of new low background BEGe detectors from enriched Ge-76 material which exhibit superior pulse shape discrimination and hence background rejection power, the development of new detector mounts, cold front end electronic circuitry, cabling and contacting schemes of ultra low mass and radiopurity, as well as the implementation of a retractable hybrid liquid argon veto system consisting of photomultipliers and silicon photomultipliers coupled to fibers which efficiently rejects all backgrounds that induce scintillation light in the liquid argon.

It is envisaged to be comprised of large-, medium- and small-sized telescopes (23m, 10-12m and 4m mirror aperture, respectively). Within the scope of the FlashCam project, a novel camera for the medium-sized telescopes of CTA has been developed. Its integration follows a horizontal architecture, where the photon detector plane (hosting photosensors and preamplifiers) is a self-contained unit interfaced through analog signal transmission cables to crates containing the readout electronics. The FlashCam design features fully digital readout and trigger electronics based on commercial ADCs and FPGAs as key components. In this way different type of digitization schemes and trigger logics can be implemented, without exchanging any hardware. The data transfer from the camera to a server is Ethernet-based, and processing rates (including event building) up to about 2 GBytes/sec have been achieved. Together with the dead-time free signal digitization this allows to operate at trigger rates up to several tens of kHz. Extensive tests and measurements with a 144-pixel setup (equipped with photomultipliers and electronics) have been performed, the results of which will be reported. In addition, the status of the preparations for a 1764-pixel prototype with full-scale mechanics and cooling system will be presented.

To cope with the corresponding rate increase, the ATLAS detector needs to be upgraded. The upgrade will proceed in two steps: Phase I in the LHC shutdown 2018/19 and Phase II in 2023-25. The largest of the ATLAS Phase-1 upgrades concerns the replacement of the first muon station of the high-rapidity region, the so called New Small Wheel. It employs eight layers of micromegas detectors (MM) and eight layers of small-strip Thin Gap Chambers (sTGC). This configuration copes with the highest rates expected in Phase II and considerably enhances the performance of the forward muon system by adding triggering functionality to the first muon station. We describe the limitations of the present muon detector and the expected improvements, the requirements for the NSW, the layout, and the detector design, including trigger & readout electronics based on a new design front end ASIC and the first deployment of a new ATLAS off-detector readout architecture based on commercial components. We will conclude with an update of the status of the project and the steps towards a complete operational system, ready to be installed in ATLAS in 2018/19 Summary This oral presentation will be on behalf of the ATLAS Muon Collaboration Primary Authors: ALEXOPOULOS, Theodoros (National Technical Univ. of Athens (GR)) <theodoros.alexopoulos(a)cern.ch> Co-authors: ZIMMERMANN, Stephanie Ulrike (Albert-Ludwigs-Universitaet Freiburg (DE)) <stephanie.zimmermann(a)cern.ch> Abstract presenters: ALEXOPOULOS, Theodoros Track classification: Sensors: 1c) Gaseous Detectors Experiments: 2a) Experiments & Upgrades Presentation type: --not specified-- Comments: This talk is on behalf of ATLAS Muon Collaboration

Key parameters are 1Mega 200µm square pixels, single 12.4 keV photon detection and a dynamic range to 10000/pixel/image. The developed sensors, ASICs, PCB-electronics and FPGA-firmware acquire individual images per bunch at 27000 bunches/s, packed into 10 bunch-trains/s with a bunch separation of 220 ns. Bunch-trains are handled by 352 analogue storage cells within each pixel of the ASIC and written to written during the 0.6msec train delivery. Random addressing provides reusability of each cell after an image has been declared as low-quality. Digitization is performed between trains (99.4 msec). The talk will introduce all functional blocks, concentrating on the DAQ-chain PCB-electronics: a dense area of 1024 ADC-channels, each with a pickup-noise filtering and sampling of up to 50 MS/s/ADC and a serial output of 700 Mbit/s/ADC. FPGAs operate the ASICs synchronized to the bunch structure and collect the bit streams from 64 ADCs/FPGA. Pre-sorted data is transmitted on 10 GbE links out of the camera head using the time between trains. The control and monitoring of the camera with 700 A current consumption is based on a micro-controller and I2C bus with an addressing architecture allowing many devices and identical modules. The high currents require planned return paths at the system level. First experimental experience of the constructed components will be presented.

CsI(Na) crystals at temperatures of ~-100 ℃ have the best performance in several candidate crystals. An experiment called CINDMS is proposed for WIMPs direct searches based on the CsI(Na) crystals detector by IHEP. The 1T-scale experimental threshold is expected to be in the world advanced level through the background estimates. The initial stage of a 50kg scale experiment called CINDMS50 is under construction at Daya Bay neutrino experiment underground laboratory for the accumulation of technology. CINDMS1T or more large-scale experiment may be located deep underground laboratory of Jinping Mountain in Sichuan, China.

We propose a novel front-end architecture aimed at reducing dead time by introducing multi signal paths in each pixel cell. A prototype chip using 0.18um six-metal standard CMOS process is consisting of 16 x 16 pixels. Each pixel has 200um pixel pitch and contains two signal paths. Two preamplifiers, eight comparators, three 15-bit counters, switching circuits, and a 30um x 30um input pad are included in a pixel. Each preamplifier has feedback capacitor and feedback resistor. We use a transistor as a feedback resistor to control its resistivity. When the preamplifier integrate charge from the input pad, the gate voltage of the transistor is lower than threshold voltage to have high resistivity. After readout the input current pulse, the transistor is turned on for fast reset. The two preamplifiers are connected to the input pad via the switching circuit respectively. The switching circuit allows only one preamplifier to connect the input pad at a time. After current pulse coming to one amplifier through the switching circuit, the switching circuit changes its connection to reduce dead time of a pixel. Each output of the two preamplifiers feed four comparators with different thresholds respectively. These four comparators perform quantization of the preamplifier output amplitude to distinguish incident X-ray photon energy. The chip will be fabricated in June 2014 and post layout simulation results will be presented in TIPP 2014.

In the FNAL 2009 beam test, it was found that the prototype calorimeter of 30 layers could meet the stringent requirements of the ILD. Following this, efforts has been made to develop a more feasible ECAL in terms of performance, size and cost. With a more compact readout electronics and improved PPD, 2 layers of embedded front end electronics technological prototype was fabricated using 3 layers of 180x180mm^2 ECAL base unit(EBU), in which each EBU has 144 channels of 45x5mm scintillator strip coupled with the improved PPD. The two layers are arranged orthogonally and by using the Strip Splitting Algorithm(SSA), we could create a fine granularity of 5x5mm^2 for the Particle Flow Algorithm application. The layers were tested at DESY and the results of this beam test shall be presented. In addition, various studies has been made on the scintillator strip in order to further improve the ScECAL’s performance such as to reduce the dead volume by PPD etc. The findings of these studies shall also be discussed and compared with the simulation results. Summary The ScECAL technological prototype shows no significant problems operating in a multilayer configuration and the SSA works well. The results from the beam test shows good energy deposit, low noisy or dead channel ratio and good scintillator uniformity. By modifying the scintillator strip shape and configuration, these performance can be further improved.

The detector is comprised of tightly-packed optically-isolated water tanks, each 5m tall and 7.3m in diameter, which are instrumented with 4 Hamamatsu photomultiplier tubes. This allows the PMTs detect the secondary charged particles that are produced when high energy (100 GeV - 100 TeV for HAWC) gamma rays and cosmic rays interact with the atmosphere. Though the detector is under construction, the DAQ has been operating and expanding with the detector as tanks are added. The DAQ is designed to handle a final event trigger rate of >15 kHz with high uptime (>99%) and low latency (<5 s), while also analyzing events with multiple triggers and reconstruction algorithms in real time. This is achieved using a modular system based on inexpensive hardware components and open source technology for transferring data (ZeroMQ). This flexible framework is agnostic to the type of data that is transferred and it could easily be applied to other experiments. We will explain the motivation for this design, describe the DAQ in detail, and present the performance of the detector.

The new promising neutrino programs request the higher performance of the detectors. It is proposed to increase the photoelectron detection efficiency of the PMT used in neutrino experiment. The researchers in IHEP designed a new type of MCP-PMT. The small MCP unit instead of the large Dynode, the transmission photocathode and the reflection photocathode were assembled in the same glass shell to form nearly 4 pai photocathode effective area to enhance the efficiency of the photoelectron detecting. Some researchers and engineers in institutes and companies in China come together to manufacture and research this type of PMT based on the MCPs. After two years R&D work, several 8 inch prototypes were produced and there performance was carefully tested in our Lab. The MCP-PMT performance test system was built in our Lab for better performance test. The characteristics of the photocathode were carefully researched by testing the I-V curve, the QE, and the QE-map for the 8 inch area photocathode uniformity. Also we measured the charge spectrum to confirm its ability for the single photoelectron spectrum. More simulation and experiment work have already done to develop an 8 inch prototype module for the MCP-PMT designed in IHEP, and the detailed will be described in this formal manuscript.

These considerations, together with the physics needs and beam structure of CLIC, push the technological requirements to the limits and imply a very different vertex detector than the ones currently in use elsewhere. A detector concept based on hybrid planar pixel-detector technology is under development for the CLIC vertex detector. It comprises fast, low-power and small-pitch readout ASICs implemented in 65 nm CMOS technology (CLICpix) coupled to ultra-thin sensors via low-mass interconnects. The power dissipation of the readout chips is reduced by means of power pulsing, allowing for a cooling system based on forced gas flow. In this talk, the CLIC vertex-detector requirements are reviewed and the current status of R&D on sensors, readout and detector integration is presented.

Laser mass spectrometry is one of the most beneficial applications of this detector, but these detectors can be successfully used in other areas where one-dimensional spatial detection of charged and neutral particles is required. In general dimensions and resolving capacity of the detector are determined by collector’s number which collects the electrons charge, its dimension and pitch. Each collector has its own charge to digit converter completed bodily on one semiconductor chip. Charge to digit conversion mechanism is defined by direct calculating charge’s portions (number of electrons) drops to collector. To ensure that sensitivity allows registering of individual ions, the detector has an integrated assembly of two microchannel plates arranged in front of the surface of the receiving electrodes. Structurally, the detector is designed as a ceramic-based monoblock, which is mounted on the chip detector assembly of microchannel plates and the necessary interface connectors. Overall dimensions of the detector assembly is 40x25x5mm. Size of the sensitive area is 2x10mm.

Abstract content The best jet energy resolution required for precise physics measurements at ILC is achievable using a Particle Flow Algorithm (PFA) and highly granular calorimeters. As it was shown by CALICE international R&D collaboration, the silicon-tungsten imaging electromagnetic calorimeter provides the best granularity and jet resolution.

All chosen technologies should be reliable and scalable for a mass production of a future detector. We report on the current status of R&D, in particular, on beam, cosmic and charge injection tests of the technological prototype and on the tests of ECAL mechanical structure with embedded fiber Bragg grating optical sensors.

See below a detailed summary of your submitted abstract: Conference: Tipp 2014 - Third International Conference on Technology and Instrumentation in Particle Physics Submitted by: FUENTES ROJAS, Cristian Alejandro Submitted on: 28 January 2014 17:07 Title: A power-pulsing scheme for the CLIC vertex detector and its 3D integration Abstract content The vertex detector is the innermost detector at the proposed CLIC linear electron-positron collider. It is composed of several layers of pixel sensors and readout ASICs, and the barrel region is made of “ladders”. The precision physics requirements limit the material budget for sensors, readout, support, cooling and cabling to less than 0.2% of a radiation length (X0) per detection layer. However, the power consumption of the readout electronics strongly impacts the required low material budget of the detector. To reduce the cable and cooling material, the average power per unit area has to be small (<50 mW/cm^2). The collision at CLIC will occur in bunch crossings every 0.5 ns during a bunch train of 156 ns. The time between consecutive trains is approximately 20 ms. Turning on the readout ASICs during the bunch trains and keeping them idle in the other part of the cycle will therefore significantly reduce the average power dissipation. The use of this beam duty cycle to reduce the average power is known as power-pulsing. The use of a power-pulsing scheme implies that the ASIC current consumption has to change suddenly from its idle value (few hundreds of mA) to full load (more than 40 Amps for a single ladder composed of 24 ASICs) within a few microseconds, then remain constant for enough time to record and process the events (few tens of microseconds) and finally drop back to the idle current value. During the bunch train, the power consumption is at its maximum and constant, and the supplied voltage for the analog components has to remain within 5% of the nominal voltage in order to allow for a correct functioning of the readout ASICs. The latter is particularly challenging, considering the big transient that takes place before the readout process. The analog and digital components of the ASICs have different constraints and therefore will be powered separately. A power-pulsing scheme based on a controlled current source allows achieving a material contribution of 0.1% of X0, which is expected to be reduced as the silicon capacitors technology improves. It consists of a controlled back-end current source that charges silicon capacitors in the ladder with low current during the idle time. In this way, the charging current is reduced to less than 100 mA for a whole ladder. The charge accumulated in these capacitors is then delivered to the ASICs during the bunch crossing time and the voltage is regulated using Low Dropout Regulators (LDOs). A prototype of this back-end current source was implemented using an FPGA. A dummy load emulating the power consumption of the analog and digital components has been implemented. In order to consolidate the proposed scheme the integration of such a system was studied. This implementation requires the use of through silicon vias, silicon capacitor die structures, and 3D connections to an LDO and a low mass interconnection cable. This talk will present the proposed powering scheme and the possible solutions of the 3D integration problem.

A DEPFET sensor, by the integration of a field effect transistor on a fully depleted silicon bulk, provides simultaneously position sensitive detector capabilities and in-pixel amplification. The characterization of the latest DEPFET prototypes has proven that a comfortable signal to noise ratio and excellent single point resolution can be achieved for a sensor thickness of 50 micrometers. The close to final auxiliary ASICs have been produced and found to operate a DEPFET pixel detector of the latest generation with the required read-out speed. A complete detector concept is being developed for the Belle II experiment at the new Japanese super flavor factory. DEPFET is not only the technology of choice for the Belle~II vertex detector, but also a solid candidate for the ILC. Therefore, in this paper, the status of DEPFET R&D project is reviewed in the light of the requirements of the vertex detector at a future electron-positron collider.

Abstract content The frontier evolution of a gaseous tracking particle detector technology has been moved in developing Micro-Pattern Gas Detectors that can achieve unprecedented spatial resolution, high rate capability and large sensitive area. However, also the geometry of such kind of tracking detector, in spite of the particular technology used, has to be known with a precision of the order of few tens of μm. The relative position of each detector with respect to a reference system is usually measured through optical sensor elements (CCDs, lenses, light sources), but also any deformation (bending, strain, torsion) with respect to its ideal shape has to be monitored as well. From this consideration, a real-time sensing technology capable to detect any curvature and deformation of a detector with a resolution of few tens of μm is desirable. However any sensor to be integrated with the detector itself should ideally comply with many requirements in terms of radiation hardness, insensitivity to magnetic field, and so on. Fiber Bragg gratings (FBGs) seem to provide a suited solution. In fact, the fiber itself can tolerate very high levels of radiations, is insensitive to magnetic field and electromagnetic noise, and FBGs are intrinsic strain and temperature sensors with wavelength-encoded information, offer high multiplexing capability with reduction of cabling complexity and linear output. In this work FBG technology is proposed as suitable sensing solution for the real-time deformation monitoring of a tracking particle detector. As a demonstrative target, some FBG sensors have been integrated with a miniature detector support panel in order to investigate their potentialities/capabilities in detecting local strain and thus bending. Preliminary experimental results are presented and discussed. Summary Our case of study is to use an FBG sensors with a micromegas (an abbreviation for “micro mesh gaseous structure” (MM)), that is a micro patter gas detector. One mandatory issue for the correct operation of the MM detector is a precise monitoring of its panels’ flatness/deformation. The basic idea, proposed here for the first time, relies with the development of a deformation monitoring system based on FBG technology, where several FBG strain sensors are surface attached to both detector support panels. Measuring strain on both sides of the panel it is possible to obtain its local curvature that is related to the second derivatives of the shape described by the bent surface. Actually, if a planar surface is bent, a positive strain (tensile) is induced on a side and a negative strain (compressive) is induced on the other one: curvature is proportional to the their relative difference. On the contrary, if a same sign strain is measured on the two sides of the surface, a longitudinal deformation of the surface can be derived. Following this idea, the whole surface of the support panels can be subdivide into a proper number of elements that undergo simple deformation. Each element will be monitored by using FBGs attached to the surface of the panel. A mechanical Finite Element Method analysis of a full size support panel is necessary in order to determine the number and the dimension of these elements, taking into account the mechanical properties of the panel and performance requirements. The sensing principle of a fiber Bragg grating can be expressed as 〖∆λ〗_B/λ_B =S_ε ε+S_T ∆T where λB is the original Bragg wavelength under strain free and initial temperature condition, ΔλB is the variation in Bragg wavelength due to applied strain ɛ and temperature variation ΔT, and Sɛ and ST are the sensitivity coefficients to strain and temperature, respectively. It is worth noting that in order to measure the strain of an host material, temperature compensation of the FBG sensor is required. The resolution of these technology is of the order of 1 με , suitable for the physical requirements on the detector geometry. The obtained results prove that the proposed approach has the potentialities to permit a continue monitoring of the deformation and bending of the detector.

See below a detailed summary of your submitted abstract: Conference: Tipp 2014 - Third International Conference on Technology and Instrumentation in Particle Physics Submitted by: SCHWEGLER, Philipp Submitted on: 28 January 2014 12:51 Title: High-Rate Properties of Drift Tube Chambers for HL-LHC Abstract content The Monitored Drift Tube (MDT) chambers of the ATLAS experiment provide muon track reconstruction with a spatial resolution of about 35 µm and efficiency of almost 100% up to the maximum expected background rates at nominal LHC luminosity. For much higher background rates, as they are anticipated for LHC luminosity upgrades (HL-LHC), sMDT chambers with 15 mm tube diameter, which is half the diameter of the MDT chambers, have been developed. Compared to MDT chambers, they suffer much less from space charge caused by background hits and provide more redundancy due to the higher packing density of the drift tubes. In the existing MDT front-end electronics, bipolar shaping is used to eliminate the long signal tail caused by the slowly drifting ions and to guarantee baseline stability at high rates. The undershoot of the bipolar shaping causes, however, signal pile-up of fast successive pulses. The impact of signal pile-up is equivalent to a higher discriminator threshold for the subsequent pulse and implies additional time slewing and degradation of the detection efficiency. A technical solution consists in an active baseline restorer. We present measurements of (s)MDT chambers under irradiation with the existing front-end electronics and with an alternative front-end chip featuring active baseline restoration and compare the performance. We also report on the development of a new version of the MDT front-end chip as a replacement for the existing one and with the option of a baseline restorer for future electronics upgrades. Summary The ATLAS Monitored Drift Tube (MDT) chambers consist of aluminum tubes with 30 mm diameter and a central sense wire with 50 µm diameter set to a potential of +3080 V. The drift tubes are operated with Ar/CO₂ (93/7) gas mixture at 3 bar absolute pressure, resulting in a gas amplification of 2×10⁴. The maximum electron drift time for hits near the tube wall is approximately 700 ns, ions can drift for several milliseconds causing long tails in the corresponding pulse shapes. The existing ASD (Amplifier-Shaper-Discriminator) front-end chip has been optimized for typical pulses of muon and background hits at rates of up to a few hundred kHz per channel. Bipolar shaping is used for baseline restoration, compensating partly the long ion tails. The typical time needed to arrive at the baseline after a hit is approximately 500 ns which is sufficient for the referred rates and the typical lengths of the MDT pulse trains. For the high luminosity upgrade of the LHC (HL-LHC), new drift tube chambers (sMDT) with reduced tube diameter - 15 mm instead of 30 mm - have been developed. They are operated with the same gas mixture and amplification as the 30 mm MDTs, leading to an operating voltage of 2730 V. As the drift velocity in the gas decreases with increasing drift radii, the maximum drift time is reduced from about 700 to 185 ns, resulting in considerably shorter pulse trains. This allows to operate the sMDT chambers at much higher rates with high efficiency. Measurements of sMDT chambers equipped with the existing ASD chip under photon and proton irradiation at rates of up to 1.5 MHz per channel show a considerable gain in the 3σ efficiency of sMDTs compared to MDTs with 30 mm diameter at high background rates. The improvement is limited, however, by the undershoot of the bipolar shaping and the long baseline restoration time of approximately 500 ns, respectively. Simulations suggest that reducing the baseline restoration time has the potential to improve the efficiency at rates of 1.5 MHz per channel from ~61% to ~76%. With increasing rates the yield is even higher. A possible approach for faster baseline restoration has been implemented in the front-end chip of the ATLAS Transition Radiation Tracker (TRT), the ASDBLR chip, with active baseline restorer (BLR). We present measurements and simulations of such a chip with active baseline restoration on sMDT and MDT chambers and evaluate the possible improvement on the efficiency and spatial resolution. A new version of the ASD chip is in development as a replacement for the existing one, with the option of a baseline restorer for future electronics upgrades. First simulation results with the new ADC chip will be shown.

To cope with considerably increased background, a pixel vertex detector (PXD) based on DEPFET technology has been developed. The PXD consists of two layers of DEPFET sensor modules located at 1.8 and 2.2 cm radii. Each module has a sensitive area, which is thinned down to 75 μm and steered with three types of ASICs: Switcher, Drain Current Digitizer (DCD) and Data Handling Processor (DHP). Switcher chips are designed to steer the pixel matrix of the sensitive area. The DCD chips digitize the drain current coming from the pixels. All ASICs will be directly bump-bonded to the balcony of the all-silicon DEPFET module. Its excellent spatial resolution (in the order of several microns) and low material budget was one of the decisive factors determining the choice of this technology for the first time. We report on the current status of the front-end electronics development, including the recent results from the first full-scale module prototype and chip testing. Summary The Belle-II pixel detector (PXD) has been developed based on DEPFET technology. The PXD requires three types of steering front-end electronics, and the development of the Data Handling Processor (DHP) is currently imperative. The DHP is designed to steer the readout from the DEPFET matrix by sending the control signals to the other two chips and sending the data off the module to the back-end data handling hybrid over a 15 m long electrical output link with a rate of 1.6 Gbps. Such high performance constraints for the digital data processing make the DHP implementation extremely challenging. Several conceptual solutions for the digital data processing blocks were proposed and implemented. Currently, three prototype DHPs have been produced with different technology and the first production version designed with a 65-nm standard CMOS technology has been delivered. The chip is currently under testing and is expected to be the production chip version, suitable for assembly on PXD modules.
