We present the development and test of a readout system which consists of an ATCA crate, with high-speed backplane, front-end cards based on custom ATCA blades and custom readout units. The flexibility and modularity of the system makes it a powerful tool to be used in simple setups like cosmic stands or test beams, as well as allowing for the integration into a more complex DAQ framework. It will be used for Micromegas detector certification but also for the readout of a Micromegas prototype detector in the ATLAS experiment. The certification applications include small to medium size lab and test beam setups as well as a 32-64k channel test facility for the certification of the Micromegas detectors for the ATLAS muon system upgrade. The integration of this system into the complex ATLAS online TDAQ will allow us to read out a Micromegas prototype detector with 4096 channels during the upcoming LHC run period.

The track parameter resolution provided by FTK enables the HLT trigger to identify efficiently and reconstruct significant samples of fermionic Higgs decays. Data processing speed is achieved with custom VLSI pattern recognition, linearized track fitting executed inside modern FPGAs, pipelining, and parallel processing. One large FPGA executes full resolution track fitting inside low resolution candidate tracks found by a set of 16 custom Asic devices, called Associative Memories (AM chips) [2]. The FTK dual structure, based on the cooperation of VLSI dedicated AM and programmable FPGAs, is maintained to achieve further technology performance, miniaturization and integration of the current state of the art prototypes. This allows to fully exploit new applications within and outside the High Energy Physics field. We plan to increase the FPGA parallelism by associating one FPGA to each AM chip. The FPGA configures and handles the AM and provides a flexible computing power to process the shapes selected by the AM. The goals of this new elementary unit made of 2 chips are: maximum parallelism exploitation, low power consumption, execution time at least 1000 times shorter than the best commercial CPUs, distributed debugging and monitoring tools suited for a pipelined, highly parallelized structure, high degree of configurability to face different applications with maximum efficiency. We report on the design of the FPGA logic performing all the complementary functions of the pattern matching inside the AM. We also show the results of the simulation of the AM and FPGA logics attached together.

An SOI wafer is utilized for sensor and electronics. The top silicon is used for SOI-CMOS circuit, and the substrate is used for a radiation sensor. There is a buried oxide layer between two silicon materials, and these are connected each other through Tungsten via. SOI-CMOS circuit has smaller parasitic capacitance compared with bulk CMOS, and therefore high-speed, low noise and low power circuits can be fabricated. Since a bump bonding is not used, the sensors have high gain with smaller pixel size. Double SOI wafers are also available. In this case, the middle SOI layers are used for shield layer against the back-gate effect and cross talk. When the voltages are applied in the middle layer, the distribution of charge traps caused by radiation in the silicon oxide can be controlled which helps to enhance radiation tolerance. KEK has organized Multi Project Wafer (MPW) runs twice a year and several types of SOI detectors has been developed and evaluated using IR laser and radiation sources. We are also trying to solve existing problems such as sensor-circuit crosstalk and radiation hardness by utilizing double SOI wafers. In this presentation, evaluation test results of up-to-date SOI pixel detectors will be shown.

The ATLAS Level-1 muon trigger rate is dominated by fake triggers in the Endcap region (|ƞ|>1) caused by charged particles originating from secondary interactions downstream of the interaction point. After the LHC phase-1 upgrade, forseen for 2018, the Level-1 muon trigger rate would saturate the allocated bandwidth unless new measures are adopted to improve the rejection of fake triggers. ATLAS is going to improve the trigger selectivity in the region |ƞ|>1.3 with the addition of the New Small Wheel detector as an inner trigger plane. To obtain a similar trigger selectivity in the barrel-endcap transition region 1.0<|ƞ|<1.3, it is proposed to add new RPC chambers at the edge of the inner layer of the barrel muon spectrometer. These chambers will be based on a three layer structure with thinner gas gaps and electrodes with respect to the ATLAS standard and a new low-profile light-weight mechanical structure that will allow the installation in the limited available space. New front-end electronics, integrating fast TDC capabilities will be used. A preliminary study based on 2012 data demonstrates that the new system could reject more than 90% of the fake triggers while maintaining high trigger efficiency. This will allow to keep a relatively low momentum threshold, while matching the rate requirements of both Phase-1 and Phase-2 LHC runs.

ROB boards have shown an excellent performance during LHC operation and are expected to continue their operation safely during all LHC Phase 1 up to 2022. Present LHC upgrades for Phase 2 foresee an increase of instantaneous luminosity up to 7 · 10^34 cm^−2 · s^−1 which will increase significantly the expected hit rate. Moreover, CMS is studying to increase the Level 1 Accept (L1A) latency of the trigger signal from 3.2 μs to 20 μs to allow including tracking subdetector information into the Level 1 trigger decision and also the L1A frequency from 100 kHz maximum to up to 1 MHz, in order to accommodate the increase of trigger rate due to the higher luminosity. ROB operation under such conditions has been studied and tested in the laboratory and results are presented in this paper.

Hi, I'm a little confused. When I looked last week the deadline for abstracts was ... tomorrow (Jan 31). Now it seems to be Feb 28. But the abstract submission process still says that abstracts will be selected for inclusion and the results announced on Feb 15. I guess you're in the process of pushing back the deadlines a bit? I'll still try to get a couple of abstracts in this week but was trying to figure out if I've missed something. Thanks, William

The radiation exposure of residents remains extremely a serious problem in Japan. The capability of gamma-ray imaging with good angular resolution is a key feature for identification of radiation hotspots and effective decontamination operation. A detector using Compton kinematics is one of the best candidates. Some Compton cameras for such purpose are being developed so far. However, they are not sufficient to cover a wide contamination area with the dose rate in air of <1µSv/hour around the Fukushima Power Plant because of their low detection efficiency and/or very high cost. Thus we developed a novel Compton camera I (Gamma Eye) with high sensitivity and low-cost. It consists of 2 arrays of detectors which act as a Compton scatterer and absorber. Energies deposited by Compton scattered electrons and subsequent photoelectric absorption measured by photomultipliers are used for image reconstruction. Each array consists of 8 large CsI(Tl) scintillator cubes, 3.5cm on a side, which are inexpensive and have good energy resolution. The 2 arrays are separated by 40cm to provide a 60-degree wide field of view as well as to keep position determination accuracy < 5 degree. The imaging capability was verified by test measurements in Fukushima Prefecture together with the laboratory tests.

Among these samples, the sensors produced at VTT (Finland), 100 μm thick, have been processed to obtain active edges, which considerably reduce the dead area at the periphery of the device down to 50 μm per side. This feature, together with the very reduced material budget, makes them attractive candidates to instrument the inner layers of the upgraded pixel system at HL-LHC. n-in-p sensors, 200 μm thick, with a standard guard-ring, produced by CIS (Germany) are manufactured without an handle-wafer and they represent reliable and cost-effective detectors to cover the large surface of the outer layers of the new pixel system. The different flavors of n-in-p pixel sensors are characterized by means of scans with radioactive sources and beam tests at the CERN-SPS and DESY. The results of these measurements will be discussed for devices before and after irradiation up to a fluence of 1.5x1016 neq cm-2 . The charge collection and tracking efficiency will be compared for the different sensor thicknesses.

Its main goal is to measure the branching ratio of the ultra-rare decay K+→π+ννbar with 10% accuracy and background contamination at the 10% level. Given the tiny branching ratio of this decay, O(10E-10), to fulfil such request the main background process K+→μ+ν (BR ~63%) must be suppressed by a rejection factor of 4x10E-13. This is accomplished by using a combination of kinematical cuts (8x10E-6), the different power of penetration through matter of pion and muon (10E-5) and a further 5x10E-3 suppression factor provided by a RICH detector in the momentum range 15-35 GeV/c. The RICH consists of a vacuum-proof cylindrical vessel with 4 m diameter, about 18 m long, filled with Ne gas at atmospheric pressure. The Cherenkov light is reflected by a mosaic of 20 hexagonal mirrors with 17 m focal length and collected by about 2000 photomultipliers. The RICH will provide the pion crossing time with a resolution of ~100 ps, to minimize wrong matching with parent kaons measured by an upstream detector and also used as a fast information to the NA62 trigger system. The construction of the detector is almost completed in view of the first NA62 run, foreseen in fall 2014. New and final results of the prototype tests at CERN, an updated description of the detector and the status of the construction, installation and commissioning will be presented, as well as the status of the RICH based customized readout electronics and trigger system.

Hence the need to use a facility where a high energy particle beam or cosmic rays can be used while the detectors under test are subjected to a high particle flux. The new Gamma Irradiation Facility (GIF++) in preparation at CERN will cover an area of about 170 m2 with a height of 4.8 m and is expected to be completed by the end of 2014. It will be equipped with a 14 TBq 137-Cs source and will benefit of a muon beam with E>100 GeV for 6-8 weeks/year. The facility will be instrumented with the user infrastructure necessary to operate and test detectors, consisting in systems for detector control and monitoring, environmental and radiation sensors, a beam tracker and a large area cosmic ray test stand. A common DAQ system will be also provided. The above infrastructure, being built within the AIDA framework, is presented in this paper. The characteristics and potentialities of all of its systems are described, together with their level of flexibility and the information which will be available to the users.

The counter design is based on ASHIPH technique (Aerogel, SHifter, PHotomultiplier). Cherenkov light emitted in aerogel is collected by a wavelength shifter and detected by a photomultiplier tube based on microchannel plates (MCP PMT). For the particle identification two systems with different refractive indexes of aerogel were manufactured: with n=1.13 for the separation of pi and K mesons up to particle energy of 1 GeV and with n=1.05 for e/pi separation up to particle energy of 0.45 GeV. The construction of the aerogel Cherenkov counter is described. Main characteristics of counters measured using particles (e, mu, pi, K) produced in e+e- annihilation are presented. Summary Experiments at the VEPP-2000 e+e- collider with upgraded SND detector have been started in the Budker Institute of Nuclear Physics (Novosibirsk, Russia) in 2010. The designed parameters of VEPP-2000 are the following: center-of-mass energy is up to 2 GeV, luminosity is 10^32 cm^-2s^-1. Development of the new particle identification system based on the threshold aerogel Cherenkov counters was a part of the SND upgrade. The counter design is based on ASHIPH technique (Aerogel, SHifter, PHotomultiplier). Cherenkov light emitted in aerogel is collected by a wavelength shifter, re-emited and transported to the photocathode. A microchannel plate photomultiplier tube (MCP PMT) with multialkali photocathode is chosen as a photodetector. For the particle identification at different energies two systems with different refractive indexes of aerogel were manufactured: with n=1.13 for the separation of pi and K mesons up to particle energy of 1 GeV and with n=1.05 for e/pi separation up to particle energy of 0.45 GeV. The system with n=1.13 was calibrated with particles (e, mu, pi, K) produced in e+e- collisions. The signal magnitude from ultrarelativistic electron is 6-8 photoelectrons. This system provides pion suppression by more than two orders of magnitude in the momentum range from 0.35 to 1.00 GeV/c. The measurements of characteristics of system with n=1.05 have been done using particles from e+e->e+e- and e+e->mu+mu- reactions. The average signal from electrons is 3.5 photoelectrons.

MRPC will be used as the main detector unit. Two methods were studied. The first one is to use NINO and HPTDC, which have already be used in ALICE. And the second one is to use a self-designed ASIC with TOT function and use sampling chip to get the waveful the to caculate the time and charge. The sampling chip used here is DRS4 and anthoer multichannel ADC is needed. With these method we can get better time resolution. And the structure is not complicated. In the practical application, we can only put one board just close the output of MRPC and transfer digital data out. All the process of measurement will be done on this board. With this method, we can make system simple and get better resolution. Summary A method of the time and charge measurement of MRPC is introduced. The key techlogic is TOT measurement and fast sampling.

These detectors are particularly relevant for rare event searches like double beta decay or dark matter search. We will present recent results obtained with small gap microbulks (25 and 12.5\,$\rm\mu$m) that have been manufactured recently. Electric field simulations taking into account the holes pattern will be also be exposed. The performance in terms of gain and energy resolution will be shown for different Argon-Isobutane mixtures and for different pressures. Energy resolutions as low as 12\% (FWHM) for the 12.5\,$\rm \mu$m while for the 25\,$\rm \mu$m values of 11.5\% have been reached at 5.9\,keV. These values are very close to the minimum energy resolution that can be achieved with gaseous detectors taking into account the fluctuations due to electron multiplication. The gain follows the expected bell shape with the maximum shifted with the pressure: smaller gaps are more suitable for higher pressures. These tests confirm the suitability of small gap microbulk for rare event detection that would require operation pressures above the atmospheric.

A voxel detector is a 2D pixelated device which is able to determine the 3d coordinate (the depth of interaction) in every pixel. Thus, it can be used to reconstruct 3D-particle tracks that can be used for particle identification. We developed a method to reconstruct the depth of interaction from properties that in principle could be directly measured with an optimized semiconductor detector. We applied the method to simulation data and investigated the reconstruction results under different parameters. For an experimental proof-of-principle we used a Timepix detector with a 1 mm thick CdTe sensor and 110 µm pixel size. We evaluated data of electrons with a kinectic energy of 4.4 GeV wherefore they can be treated as minimal ionizing in our case. Despite the fact that the current Timepix cannot deliver all the necessary information for the algorithm, we successfully performed the reconstruction for electron track by employing this property (minimal ionization). The reconstruction method and recent results on the z-position resolution will be presented.

Noble gases can provide a very long electron drift distance which is required for large-scale low-background experiments such as the search for dark matter or for the neutrinoless double beta decay. Due to the higher density, xenon is often used in the liquid instead of gaseous state, which allows a larger detection mass at constant volume. However, solid xenon detectors could provide additional advantages over liquid xenon setups. We present the results of recent experiments on large xenon crystals grown from the liquid phase. We successfully measured the scintillation light from ionizing radiation in the crystal and compared it to Monte Carlo simulations. Also, we studied the drift of electrons over several centimeters. The results suggest a higher drift velocity and a better collection efficiency of secondary electrons than in the case of liquid xenon. Our work is the basis of the future development of new kind of TPC using solid xenon in combination with the Timepix detector. It would benefit from the excellent electron drift characteristics of xenon. A new detector design involving both solid xenon and the Timepix detector will be presented.

Abstract content Future calorimeters and shower maximum detectors at high luminosity accelerators need to be very radiation resistant and very fast. In this report we outline the study of the development of such detectors using microchannel plate (MCP) secondary emitters. The first proposal to use secondary emitters in such a detector can be found in Ref. [1]. Our research is based on the use of MCP secondary emitters as active elements that directly amplify the electromagnetic component in showers. A key point is that the method does not require a complete MCP/phototube with photocathode deposited on a vacuum glass container, but can use the bare MCP’s in an inexpensive and robust housing. As the photocathode fabrication is the dominant driver of the cost of current MCP-PMTs, the use of bare plates without a photocathode results in much cheaper and more robust assembly. One of the main limitations in using this technique has been the high cost of MCPs. Due to recent progress in developing MCP’s consisting of large-area glass-capillary substrates functionalized by Atomic Layer Deposition [2, 3], this approach is becoming feasible. Test beam measurements of a prototype were performed with 120 GeV primary protons and secondary beams at the Fermilab Test Beam Facility. We present proton and positron beam tests results, obtained with different type of MCP-PMT’s. Beam particles pass through a lead absorber of varying thickness, creating a shower that is detected by the MCP-PMT’s. We report here on the timing characteristics obtained in the beam tests, the dependence of the pulse amplitude on the absorber thickness, and the contribution of the Cherenkov component from the shower interacting with varying thicknesses of quartz placed in front of the MCP-PMT. We have measured a shower maximum time resolution of ~25 psec, using the DRS4 5 GS/s digitizer. [4] *corresponding author References 1. A. Derevshchikov, V. Yu. Khodyrev, V.I. Kryshkin, V.E.

Among these objectives; investigation of the ageing phenomena of high rate gaseous detectors, the ageing influences of the construction materials of the gaseous detectors, long term monitoring of gaseous detectors tolerance, planned to be used in The Compressed Baryonic Matter (CBM) experiment at the future Facility for Antiproton and Ion Research (FAIR) in Darmstadt, Germany. It is very important, in ageing studies, to sense the detector degradation, if any, in reasonable time period and with a particle rate comparable to that in real experiments. In order to reach the envisaged accuracy, several optimizations have been implemented over the design of the used counters, the setup approach and automation and the gas system. In this article, details of the experimental setup, the systematic optimization tests, studies of ageing and anti-ageing manifestations, and results of the influence of different construction materials will be presented.

In the HL-LHC conditions, we expect a luminosity of 5x1034 cm-2 s-1 and a rate about an order of magnitude higher than the present one. This, while boosting the demand of trigger performance to increase the fake rejection, the muon momentum selectivity and coverage, affects the robustness against the ageing effects. This scenario leaves the present RPC muon trigger without adequate safety margins and suggests an appropriate upgrade plan, involving both the detector, the trigger and readout electronics. We present a study for an upgrade of the ATLAS RPC system, under evaluation by the ATLAS collaboration, conceived to maintain full efficiency for the 20 years future operation scheduled. The upgrade consists mainly in installing an additional layer of new generation RPCs in the inner barrel. This will increase the redundancy and the acceptance, now reduced to 70% due to the barrel toroid magnets and services. The present RPC system performances will also benefit of a new readout electronics foreseen to cope with the upgraded ATLAS DAQ. A non-negligible side benefit of this upgrade scheme is providing ATLAS with good TOF capabilities: a prompt time resolution of few hundreds of ps, 10 m lever arm and four independent measurements will extend the ATLAS potential for new physics discoveries.

Abstract content The associative memory (AM) system is a computing device made of hundreds of AM ASICs chips designed to perform “pattern matching” at very high speed. Since each AM chip stores a data base of 130000 pre-calculated patterns and large numbers of chips can be easily assembled together, it is possible to produce huge AM banks. Speed and size of the system are crucial for real-time High Energy Physics applications, such as the ATLAS Fast TracKer (FTK) Processor. Using 80 million channels of the ATLAS tracker, FTK finds tracks within 100 micro seconds. The simulation of such a parallelized system is an extremely complex task if executed in commercial computers based on normal CPUs. The algorithm performance is limited, due to the lack of parallelism, and in addition the memory requirement is very large. In fact the AM chip uses a content addressable memory (CAM) architecture. Any data inquiry is broadcast to all memory elements simultaneously, thus data retrieval time is independent of the database size. The great computing power is also supported by a very powerful I/O. Each incoming hit reaches all the patterns in the AM system within the same clock cycle (10 ns). We report on the organization of the simulation into multiple jobs to satisfy the memory constraints and on the optimization performed to reduce the processing time. Finally, we introduce the idea of a new computing unit based on a small number of AM chips that could be plugged inside commercial PCs as coprocessors. This unit would both satisfy the need for very large memory and significantly reduce the simulation time due to the use of the highly parallelized AM chips.

The ATLAS tau trigger system combines information from the tracking and calorimetry detectors to identify the signature of tau lepton hadronic decays. Under the demanding, high luminosity environment of Run 2 at the LHC experiment (with instantaneous luminosities as large as 2x10^34 cm^-2s^-1), triggering on hadronic tau leptons requires faster reconstruction algorithms than ever before. We present two new algorithms currently being deployed: a more precise and faster calorimeter energy cluster reconstruction, and a high-speed tracking, along with their expected performance for the Run 2 experiment. Simple triggers requiring single taus suffer from severe rate limitations, despite the sophisticated algorithms used in the tau identification. To address this limitation, higher efficiency triggers implementing topological selections are designed. Using these new developments, tau triggers will provide many opportunities to study new physics beyond the Standard Model, and to get precise measurements of the properties of the Higgs boson decaying to tau-leptons. Finally, the expected feasibility of tau physics measurements in Run 2 will be presented.

The AM is the heart of the FTK and it finds track candidates at low resolution that are seeds for a full resolution track fitting. To solve the very challenging data traffic problem inside the FTK, multiple designs and tests have been performed. The currently proposed solution is named the “Serial Link Processor” and is based on an extremely powerful network of 2 Gb/s serial links. This paper reports on the design of the Serial Link Processor consisting of the AM chip, an ASIC designed and optimized to perform pattern matching, and two types of boards, the Local Associative Memory Board (LAMB), a mezzanine where the AM chips are mounted, and the Associative Memory Board (AMB), a 9U VME board which holds and exercises four LAMBs. We report also on the performance of a first prototype based on the use of a min@sic AM chip, a small but complete version of the final AM chip, built to test the new and fully serialized I/O. Also a dedicated LAMB prototype, named miniLAMB, with reduced functionalities, has been produced to test the mini@sic. The serialization of the AM chip I/O significantly simplified the LAMB design. We report on the tests and performance of the integrated system mini@sic, miniLAMB and AMB.

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. An initial upgrade (Phase0) is scheduled to be ready for the start of the second LHC run in 2015, and a further more substantial upgrade (Phase1) is planned to be installed during the LHC shutdown expected in 2018. The calorimeter trigger aims to identify electrons, photons, taus and hadronic jets. It also determines total and missing transverse energy and can further analyse the event topology using a dedicated system incorporating information from both calorimeter and muon triggers. This paper presents the Phase1 hardware trigger developments which exploit a tenfold increase in the available calorimeter data granularity when compared to that of the current system. The calorimeter signals will be received via optical fibers and distributed to two distinct processing systems. Those systems implement sliding window algorithms and quasi offline algorithms to achieve object reconstruction and identification. The algorithms are implemented on high density electronics boards which make use of recent developments in high speed data transmission and FPGA technology. The presentation reviews the physics impact along with the current status of the hardware design and early prototypes and demonstrator boards.
