Experimental measurements will be presented and compared with simulations built using GEANT4. In addition, measurements with neutron beams ranging in energy between 14 MeV and 66 MeV, produced at the iThemba LABS cyclotron facility will be used to illustrate the pulse shape discrimination capabilities of the digital data acquisition system. The potential of the device for both dosimetry and security applications will be discussed, together with the challenges of implementing a compact neutron/gamma-ray detector for use in industry.

CERN is developing methods of thresholds equalization to correct for threshold dispersion between pixels of the Medipix3RX readout chip. In this paper, we focus on the complex problem of pixel-to-pixel dead time dispersion, which cannot be corrected by simple flat field normalization, contrary to the residual threshold dispersion after equalization. In tomography, dead time inhomogeneity is responsible for ring artefacts, in addition to global underestimation of the attenuation coefficients due to pile-up. While the main methods of ring artefact correction are purely mathematical, our strategy was to develop a method based on dead time calibration to be able to remove ring artefacts and at the same time to restore the correct quantitative attenuation coefficients. Our original correction method is based on a calibrated dead time map associated to an iterative correction on the sinograms. We performed a fine analysis of dead time dispersion and compared it to our model of photonic noise propagation to validate the calibration step. The results of the pile-up correction with a single Medipix3RX ASIC bump bonded to 200 microns Silicon sensor using a standard X Ray generator showed quantitative improvements of transmission images of Al filters, increasing by a factor 3 the signal-to-noise ratio after pile up correction within the flux range [5E3 – 2E5] photons/pixel/s. We are currently validating the method on the tomographic beam line of the Brazilian Synchrotron (LNLS).

See below a detailed summary of your submitted abstract: Conference: Tipp 2014 - Third International Conference on Technology and Instrumentation in Particle Physics Submitted by: MORELLO, Gianfranco Submitted on: 30 January 2014 11:01 Title: Construction and commissioning of the KLOE-2 Inner Tracker Abstract content The KLOE-2 experiment is starting its data taking at the DAΦNE ϕ-factory at the Frascati National Laboratory of the INFN. The experiment is continuing the successful physics program of KLOE, that collected 2.5 fb-1 of integrated luminosity between 2001 and 2006. For the new data taking campaign the detector, consisting of a huge Drift Chamber and a Electromagnetic Calorimeter working in a 0.5 T axial magnetic field, has been upgraded. One of the upgrades involves the tracking system, with the insertion of a GEM-based detector in the space separating the DAΦNE interaction region and the inner wall of the Drift Chamber. The Inner Tracker, composed of four coaxial cylindrical triple-GEMs, is a kapton-based detector allowing us to keep the total material budget below 2% X0, as required in order to minimize the multiple scattering of low-momentum tracks. Novel and advanced solutions were developed to cope with the challenging problems that arose during the construction phase. The tracker achieves 200 μm spatial resolution in the transverse plane and 500 μm along the beam direction. The two coordinates are provided by a dedicated XV readout pattern coupled to the GASTONE front-end, a 64 channel ASIC with digital output specially developed for this detector. The first results from the commissioning of the detector will be shown, including the preliminary response of the detector to cosmic-ray muons and DAΦNE beam interactions.

See below a detailed summary of your submitted abstract: Conference: Tipp 2014 - Third International Conference on Technology and Instrumentation in Particle Physics Submitted by: ERHAN, Samim Submitted on: 30 January 2014 10:56 Title: The new CMS DAQ system for run 2 of the LHC Abstract content The data acquisition system (DAQ) of the CMS experiment at the CERN Large Hadron Collider assembles events at a rate of 100 kHz, transporting event data at an aggregate throughput of 100 GByte/s to the high level trigger (HLT) farm. 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.
