One of the best time resolution for single charged particles has been achieved using a photomultiplier tube based on microchannel plates (MCP-PMT) coupled with a Cherenkov radiator. The main problem of MCP-PMT is its limited lifetime due to photocathode degradation. The degradation is considered to be caused by feedback ions that bombard the photocathode and affect its photoemissive...
Aerogel is unique material with refractive index between gaseous and liquids. Due to this circumstance highly transparent aerogels are good candidates for Cherenkov radiators in RICH detectors. There are several HEP projects required excellent PID performance in the world. For some of them RICH detectors based on aerogel produced in Novosibirsk were proposed by BINP team. Among them FARICH...
As part of the R&D of the AGORA muon system (CEPC), the JINR group created a setup for testing long scintillation strips up to 4.3 meters long. This setup allows for the simultaneous examination of 16 samples of maximum length at 16 points along the strip. It is designed for long-term measurements using cosmic muons to obtain various strip parameters, including time and spatial resolution,...
In recent years, the next generation electron–positron collider projects—including CEPC, FCC-ee, and ILC, have emerged as the leading platforms for precision physics, targeting measurements of the Higgs boson, electroweak observables and flavor physics. In particular, the precision studies of charm and hadrons place the most stringent demands on particle identification (PID) over a wide...
The Circular Electron-Positron Collider (CEPC) requires efficient particle identification (PID) in the forward region, where the performance of the baseline $dN/dx+\mathrm{ToF}$ system degrades for high-momentum kaons. In particular, approximately $3\sigma$ $K/\pi$ separation up to $20~\mathrm{GeV}/c$ motivates the development of an additional Endcap Ring Imaging Cherenkov (RICH)...
The Ring Imaging Cherenkov (RICH) detector is one of the particle identification (PID) detectors employed in the Super Tau-Charm Facility (STCF). This report focuses on recent progress in RICH research, covering performance characterization and optimization, analysis of beam test and cosmic-ray test results, as well as simulation studies evaluating the PID performance of the RICH detector at the STCF.
Long scintillation strips with embedded WLS fibers are widely used in muon systems of modern experimental facilities, including future electron-positron colliders. To accurately reconstruct particle tracks and to simulate the passage of particles through the strips of the muon system, it is necessary to know the parameters of the scintillators with high accuracy: light output, attenuation...
