We present the first results of a tracking system prototype using the artificial retina algorithm for fast track finding. The system is based on extensive parallelization and interconnectivity, and allows real-time tracking with offline-like quality with a latency < 1 μs. The artificial retina algorithm has been implemented on a novel custom data acquisition board, based on commercial FPGAs, that...
To determine the accurate radiation dose for a specific small volume of tissue, confirmation of the temporal location of a target position is very important. The temporal location of the target can help improve the accuracy of target localization. A kilovoltage cone-beam computed tomography (CBCT) system mounted on a linear accelerator can verify the target on each treatment day, but this system requires...
A Head proton computed tomography (pCT) scanner based on a fiber tracker and scintillator stack range detector has been developed at Northern Illinois University in conjunction with Fermilab. We present preliminary results from beam tests conducted in 2014 at the Central DuPage Hospital (CDH) at Warrenville, IL. The scanner is described in [1], and the image reconstruction hardware and software are...
This paper presents a 16-Channel, 12-Bit, 500 MHz ADC/Data Processing Module, designed for the KOTO Experiment at the Japan Proton Accelerator Research Complex (J-PARC). Few hundreds of this 6U VME board will receive signals from various detectors of the apparatus, and will be the digitizing modules in the Experiment's Data Acquisition System (DAQ). In KOTO, the main ADC/DAQ system runs at a 125 MHz...
The NA62 experiment at the European Organization for Nuclear Research (CERN) Super Proton Synchrotron (SPS) aims to measure the Branching Ratio of the very rare kaon decay K+ → π+νν, collecting O (100) events with a 10% background to make a stringent test of the Standard Model. One of the main backgrounds to the proposed measurement is represented by the K+ → π+π0, decay. To suppress this background...
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...
The Electron Tracking Compton Camera (ETCC) has the wide energy range (0.1–2 MeV). We upgrade the recoil electron readout circuit, and the tracking algorithm. Due to this improvement, the data acquisition rate is faster than before, and the imaging quality is increased. The performance of ETCC is checked by using the test-tube with F-18 water solution. We have developed the ETCC for new medical imaging...
A typical whole-body PET scanner performs data acquisition of a patient from multiple bed positions with overlap between adjacent bed positions. An alternative acquisition mode, continuous or near-continuous bed motion acquisition, has a number of advantages over the traditional step-and-shoot mode, including uniform axial sensitivity and elimination of axial resolution artifacts. To support the super-sampling...
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.
The purely software based old data acquisition system of the COMPASS experiment at CERN is replaced by the new hybrid FPGA-software system. The two level FPGA subsystem takes over the data handling role. The hardware is built in a compact AMC form factor using a Xilinx Virtex-6 VLX130T FPGA as a data processor. The data handling includes a 15:1 data link multiplexing and complete event building in...
The Heavy Photon Search (HPS) experiment at Thomas Jefferson National Accelerator Facility (JLab) will search for heavy photons, which are new hypothesized massive vector bosons. The experiment consists of an electromagnetic calorimeter and Silicon Vertex Tracker (SVT). The SVT Data Acquisition System (DAQ) supports readout and processing of signals from 36 silicon strip sensors of the SVT. It also...
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...
In 2014, the control and data acquisition (DAQ) system for user experiments was reorganized at the X-ray free electron laser facility, SACLA. The upgraded DAQ system now supports concurrent experiments on two beamlines. In order to secure data throughput and introduce access restriction, the data stream and control communications are physically separated for each beamline. The system can handle two...
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...
In the present work we present the development of a Silicon PhotoMultiplier (SiPM)-based detection module for hybrid SPECT/MRI instruments. The module is designed for preclinical SPECT systems for mouse and rat brain imaging, but can also be exploited for clinical SPECT brain scanners. The gamma-ray detection module is designed on the well-established Anger architecture, with a continuous 5 cm χ 5...
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...
