A commercial Graphics Processing Unit (GPU) is used to build a fast Level 0 (L0) trigger system for the NA62 experiment at CERN. In particular, the parallel computing power of the GPU is exploited to perform real-time fitting in the Ring Imaging CHerenkov (RICH) detector for the L0 trigger of the NA62 experiment. Direct GPU communication using a FPGA-based board has been used to reduce the data transmission...
One of the challenging applications of PET is implementing it for in-beam PET, which is an in situ monitoring method for charged particle therapy. For this purpose, we have previously proposed two geometries for our original open-type PET scanners named OpenPET. Following our initial proposal of the dual-ring OpenPET (DROP) in 2008, we developed a whole-body prototype of DROP (WBDROP) in 2014 to show...
This work presents the first experimental results of SFERA, a multichannel low-noise readout ASIC designed for both X and γ-ray detectors for spectroscopy and imaging applications. The chip has been developed to process signals coming from solid-state detectors and CMOS preamplifiers. The design has been guided by the use of silicon drift detectors (SDDs), although the ASIC may find a wider application...
The EDELWEISS experiment, located in the underground laboratory LSM (France), is one of the leading experiments using cryogenic germanium (Ge) detectors for a direct search for dark matter. For the EDELWEISS-III phase, a new scalable data acquisition (DAQ) system was designed and built, based on the ‘IPE4 DAQ system’, which has already been used for several experiments in astroparticle physics.
Depth-of-interaction (DOI) measurement is essential for PET to reduce the parallax error, which results in improved spatial resolution while maintaining the sensitivity. One of the ultimate goals for improvement of DOI detectors is achieving their isotopic spatial resolution. For this purpose, we have developed an isotropic 3D position-sensitive PET detector named the X'tal cube detector. The X'tal...
RECENTLY, there has been great interest in the study of deriving PET event information from digitally sampled event waveforms. We have reported the feasibility of Multi-Voltage Threshold (MVT) based PET DAQ system using field — programmable-gate-array (FPGA) without ADC and TDC. The goal of this study was to extend MVT based multi-channel analog circuit and DAQ with FPGA which could be utilized for...
The Data Quality Monitoring (DQM) Software is a central tool in the CMS experiment. Its robustness and flexibility is critical for monitoring detector performance and providing fast and comprehensive feedback centrally for the experiment in realtime (Online DQM), after a full event processing with fine-grained analysis (Offline DQM), and as a validation tool to validate both the CMS software (CMSSW),...
The upgrade of the LHCb experiment, planned for 2019, will transform the experiment in a trigger-less system reading out the full detector at the maximum 40 MHz event rate. This will enable the detector to run at instantaneous luminosities of 2×1033 cm−2s−1 and probe physics beyond the Standard Model in the heavy flavour sector with unprecedented precision. The Vertex Locator (VELO) is the silicon...
We present the design for the new read out system being developed for the Phase 2 Upgrade of the ATLAS Tile Calorimeter. The front-end electronics will be replaced to address the increase in beam energy and luminosity planned for the LHC around 2023, as well as to upgrade to faster, more modern components with higher radiation tolerance. The new electronics will operate dead-timelessly, providing...
Silicon Photomultipliers (SiPMs) are rapidly developing photosensitive devices which are already used as an alternative to photomultipliers (PMT) in the newly developed calorimeters for high-energy physics. Many measurement results and SIPMs parameters based on signal amplitude histograms analysis have been published. Author presents a special automated system for scanning SIPMs surfaces with a fast...
WE have previously demonstrated a stripline readout for TOFPET detectors that can achieve significant reduction in the number of readout channels while maintaining good detection performance [1-3]. The principle of this time-based multiplexing readout is depicted in Figs. 1(a) and 1(b). As shown, a stripline receives the outputs of several photodetectors (PD). When a PD produces a signal at time t...
SuperNEMO is the next-generation (0νββ) experiment based on a tracking plus calorimetry technique. The demonstrator is made of a calorimeter (712 channels) and a tracking detector (6102 channels). These detectors front-end electronics use an unified architecture. The calorimeter and tracker can operate separately. We have an overlap between the zoning of the calorimeter and the tracker. The final...

It allows recording short duration (3–5 ns) scattered pulses with 2GHz sampling rate and 10-bit total resolution. The system consists up to 48 photo detector modules with 0–200MHz bandwidth, 1–48 simultaneously sampling ADC modules and synchronization subsystem. The photo detector modules are based on...
CORAM (COsmic RAy Mission) is an experiment carried out by INFN and the University of Salento for studying and measuring several properties of the cosmic ray flux. The CORAM detector can be used both for experimental and outreach goals and it is designed also for aereospace applications. The final Data Acquisition system (DAQ) has been implemented in order to create a compact, redundant and user friendly...
The NTUHEP group is currently designing a BGO sytem to monitor the instant luminosity by measuring the back-to-back Bhabha events for BEAST2, a special detector for the commissioning of SuperKEKB and Belle2. The experiment of energy calibration will be introduced in the paper, the result shows BGO system can detect cosic ray and the maximun event number is occurred at 15 to 20 photon-electrons.
This paper describes the route of events through both hardware and software parts of the data acquisition system (DAQ) of the COMPASS experiment at CERN which implements FPGA based event-building. Data quality control is important part of any DAQ. During development of the COMPASS DAQ, a great emphasis was put on ability to recover from errors coming from frontend electronics and on possibility to...
The Data Acquisition System (DAQ) and the Front-End electronics for an array of Kinetic Inductance Detectors (KTDs) are described. KTDs are superconductive detectors, in which electrons are organized in Cooper pairs. Any incident radiation could break such pairs generating quasi-particles, whose effect is increasing the inductance of the detector. Electrically, any KID is equivalent to a parallel...
In this paper, a data acquisition scheme that is reactive to network congestion is proposed for Internet of Things (IoT). It adjusts data acquisition rates according to the congestion level in a distributed manner, thereby alleviating and avoiding congestion as much as possible. It also makes its best effort to deliver information of high priorities in a timely manner and ensure uninterrupted sensing...
The design of a hi-Q resonant RF cavity with coupled detection scheme and associated instrumentation is reported for studying quantum vacuum within the framework of Quantum Electrodynamics (QED), the quantum theory of interaction of matter with radiation. Although this system could possibly serve in any general QED, cavity QED and RF applications in the range of a few GHz, the design was specifically...
