In high energy physics experiment trigger systems, block memories are utilized for various purposes, especially in binned searching algorithms. In these algorithms, the storages are demanded to perform like a large set of registers. The writing and reading operation must be performed in single clock cycle and once an event is processed, the memory must be globally reset. These demands can be...
An experiment to measure the spectral modification of vector mesons in nuclear medium is planned as the J-PARC E16. It will start at a J-PARC high momentum beam line in FY 2019. The number of total detector channels is 112,996.
The trigger decision is made from 2,620 ch discriminator output signals. The number is too large to handle with one module, therefore we have developed a new trigger...
The low level rf (LLRF) control system for the rapid cycling synchrotron of the
Japan Proton Accelerator Research Complex (J-PARC) started its operation in
2007. The key functions of the LLRF control system are the dual harmonic auto
voltage control, which generates superposed voltages of the fundamental
accelerating harmonic and the second harmonic in a single wideband magnetic
alloy (MA)...
Many modern large-scale facilities, like European X-ray Free Electron Laser (E-XFEL), require precise synchronisation, often down to femtosecond level. Even a very short interruption or an excessive glitch in the reference signal might break the precise time relations between subsystems. In such event, a time-consuming resynchronization process is required that renders the facility not...
As an important prototype of Deep Underground Neutrino Experiment (DUNE) far detector, ProtoDUNE single phase (ProtoDUNE-SP) with a total liquid argon (LAr) mass of 770 ton, represents the largest monolithic single-phase LAr TPC detector to be built to date. The detector elements, consisting of 6 Anode Plane Assemblies (APAs), 3 Cathode Plane Assemblies (CPAs), are housed in a cryostat that...
