The particle identification system ASHIPH (Aerogel, SHifter, PHotomultiplier) has been working in the KEDR experiment at VEPP-4M $e^{+}e^{-}$-collider (Budker INP, Novosibirsk) since 2014. The system consists of 160 aerogel cherenkov counters arranged in two layers and covers 96% of the solid angle. The volume of aerogel is 1000 liters, its refractive index is 1.05. For the photon detection we...
Modern projects require large format aerogel radiators. In 2022-2023, several unique aerogel tile were produced in Novosibirsk. Aerogel blocks larger than 200 by 200 mm in lateral size and 40, 50 mm thickness with a refractive index of 1.03 or 1.05 were fabricated. Also in 2023, for the first time in the world, samples of a multilayer focusing aerogel with dimensions of 230x230x35 mm were...
The Super Charm-Tau (SCT) Factory project is a future electron-positron colliding beam experiment with unprecedented high luminosity $10^{35}$cm$^{-2}$s$^{-1}$ at the interaction energy range from 3 to 7 GeV. The physics program of the experiment is aimed to search the phenomena beyond the standard model and its precise calibration in this energy range. The main features of the SCT Factory...
The FOOT experiment aims at measuring the differential cross sections for the production of secondary fragments in interactions between light ions (C, O) and hydrogen-enriched targets, with beam energies of up to 400 MeV/u, a topic relevant for the optimization of particle therapy treatments, which can only be addressed in inverse kinematics [1]. By extending the energy range up to 800 MeV/u,...
The Spherical Neutral Detector (SND) is intended for the study electron-positron annihilation processes operating at VEPP-2000 e+e- collider, which is located at Novosibirsk, Russia. The main part of the SND detector is a three-layer electromagnetic calorimeter (EMC).
The EMC is equipped with spectrometric channel, which provides measurement of the calorimeter signal arrival time and...
The next frontier project of nuclear physics in the United States will be the Electron-Ion Collider (EIC), planned to be built in the Brookhaven National Laboratory (BNL). Excellent particle identification (PID) is one of the key requirements for the EIC central detector. Identification of the hadrons in the final state is critical to study how different quark flavors contribute to nucleon...
