The HLT farm selects interesting events for storage and offline analysis at a rate of around 1 kHz. The DAQ system has been redesigned during the accelerator shutdown in 2013/14. The motivation is twofold: Firstly, the current compute nodes, networking, and storage infrastructure will have reached the end of their lifetime by the time the LHC restarts. Secondly, in order to handle higher LHC luminosities and event pileup, a number of sub-detectors will be upgraded, increasing the number of readout channels and replacing the off-detector readout electronics with a μTCA implementation. The new architecture will take advantage of the latest developments in the computing industry. For data concentration, 10/40 Gbit Ethernet technologies will be used, as well as an implementation of a reduced TCP/IP in FPGA for a reliable transport between custom electronics and commercial computing hardware. A 56 Gbps Infiniband FDR CLOS network has been chosen for the event builder with a throughput of ~4 Tbps. The HLT processing is entirely file based. This allows the DAQ and HLT systems to be independent, and to use the same framework for the HLT as for the offline processing. The fully built events are sent to the HLT with 1/10/40 Gbit Ethernet via network file systems. Hierarchical collection of HLT accepted events and monitoring meta-data are stored into a global file system. This paper presents the requirements, technical choices, and performance of the new system.

See below a detailed summary of your submitted abstract: Conference: Tipp 2014 - Third International Conference on Technology and Instrumentation in Particle Physics Submitted by: VAN HEIJNINGEN, Joris Submitted on: 30 January 2014 10:00 Title: Interferometric Readout for a Monolithic Accelerometer, towards the fm/rtHz Abstract content In order to make a really precise vibration sensor, a monolithic accelerometer, in which a mass is suspended by a pendulum and an inverted pendulum, is read out using a tabletop Michelson interferometer (IFO). To measure the position of the mass, a corner cube attached to the suspended mass is used. The signals in both arms of the IFO are monitored, matched and subtracted, using this differential signal as an error signal in a feedback loop driving the voice coil actuating to the other side of the suspended mass. Pursuing to be shot-noise limited from 5Hz onwards and having a upper limit to the bandwidth of about 200Hz, the resolution is pushed towards the fm/rtHz. Summary The upgrade for the Virgo Gravitational Wave Observatory (Cascina, Italy) necessitates for added sensing which has to be seismically isolated as well. Nikhef has built the compact isolator to do this, but to measure its residual motion in full assembly, no (commercial) sensor is available that is good enough to actually measure it. A novel vibration sensor is built at Nikhef by using an interferometric readout of a monolithic accelerometer. This system is also being researched at Nikhef in a fiber version, so that it can be used in monitoring the vibration in the magnetic and radiation environment of the quadrupole magnets a (future) linear collider such as CLiC or the ILC.

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.
