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. This location provides vastly improved shielding from cosmogenic events which will reduce interference of known backgrounds particles.

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.
