Hadron fluence monitors based on static random access memories (SRAMs) are being used at CERN and have been proposed for proton therapy facilities. Some of the limitations state art related to usage separate components sensing upsets reading them out, as these increase power consumption, board complexity its size. Moreover, in some cases, due radiation-tolerance requirements, readout logic is fixed it cannot be updated once system has implemented. In this work, we show how overcome mentioned...
On-detector digital electronics in High-Energy Physics experiments is increasingly being implemented by means of SRAM-based FPGA, due to their capabilities reconfiguration, real-time processing and multi-gigabit data transfer. Radiation-induced single event upsets the configuration hinder correct operation, since they may alter programmed routing paths logic functions. In most trigger acquisition systems, from several front-end modules are concentrated into a board, which then transmits...
Abstract Single photon sensitive detectors used in high energy physics are, some applications, required to cover areas the size of several m 2 , and more specifically very strong demand with an ever finer imaging timing capability for Cherenkov Ring Imaging Detector (RICH) configurations. We are evaluating Large Area Picosecond Photo-detector (LAPPD) produced by INCOM company, as a possible candidate future RICH detector upgrades. In this work we perform tests on second generation device,...
Abstract Hadron fluence monitors based on static random access memories (SRAMs) are in use at particle accelerators for the protection of electronics and proton-therapy facilities measuring secondary neutrons. One shortcoming current solutions is that they necessitate SRAMs to detect radiation-induced single event upsets require additional components transfer counts from radiation area. This approach limits practicality sensors due their power requirements, increased board complexity, larger...
Since 2018, an Proximity Focusing Aerogel Ring Imaging Detector (ARICH) efficiently separates hadrons in the forward end-cap of Belle II spectrometer. Cherenkov photons emitted double-layer aerogel radiator are expanded 16-cm space and detected on photon detector, which consists 420 hybrid avalanche photodiodes rear readout electronics operating threshold mode. Each sensors requires six different high voltages a supply four low for electronics. Because power dissipation, system also includes...
As a part of the LHCb RICH Future upgrades experimental program, we studied hydrophobic aerogel tiles from Chiba University during 2021 CERN SPS testbeam. In 180 GeV/c proton beam, tested aerogels with different refractive indices and thicknesses. The Cherenkov light radiated was focused by lens registered an array MAPMTs. number detected photons per ring for 2 cm thick tile index 1.03 around eight in good agreement Monte Carlo simulation. We estimate photon production yield to be about 50...
Hadron fluence monitors based on static random access memories (SRAMs) are in use at particle accelerators for electronics protection and proton therapy facilities measuring secondary neutrons. A shortcoming of conventional solutions is that they require the SRAMs to sense radiation-induced single event upsets additional components transfer counts external systems outside radiation area. This approach limits practicality sensors due their power requirements, increased board complexity,...
High Energy Physics experiments usually require radiation-tolerant electronics for on-detector operation. When possible, it is preferable to use commercial off-the-shelf components. For purely digital functions, such as data aggregation, processing and transfer, static RAM-based Field Programmable Gate Arrays (SRAM-based FPGAs) are increasingly being used on outer sub-detectors. While these devices offer great advantages in terms of flexibility performance, they pose important issues related...
