Cherenkov radiation has characteristics that enable us to measure the velocity of the parent charged particle by means of the number of photons, the specific polar angle of the photon emission, and the timing of the photon detection. The precision of the velocity measurement depends on how well such information can be exploited. In fact, innovative developments of radiators, photosensors and...
At the Belle II experiment a Time-of-Propagation (TOP) counter is used for particle identification in the barrel region. This novel type of particle identification device combines the Cherenkov ring imaging technique with the time-of-flight. An overview of the operation and performance status of the TOP counter will be presented. We will discuss also a Geant-4 based Monte Carlo simulation,...
The Aerogel Ring Imaging CHerenkov (ARICH) detector is a key component of the Belle II experiment at the SuperKEKB collider in Tsukuba, Japan, designed to provide excellent charged particle identification in the forward region. The experiment aims to accumulate 50 times more data than its predecessor to enable precise studies of rare B and D meson decays, as well as tau lepton processes. The...
During the second LHC long shutdown (2019 -- 2021), the LHCb experiment underwent a major upgrade in order to be able to operate at the instantaneous luminosity of $2 \times 10^{33}~\mathrm{cm}^{-2}~\mathrm{s}^{-1}$, and remove the hardware trigger reading out every LHC bunch crossing. This instantaneous luminosity corresponds to illumination rates up to $100~\mathrm{MHz}/\mathrm{cm}{^2}$ on...
The ALICE experiment is designed to collect pp, p–A, and A–A collision data provided by the LHC, to investigate the properties of strongly interacting matter under extreme conditions of temperature and energy density. Among the ALICE particle identification (PID) detectors, the High Momentum Particle Identification Detector (HMPID) is dedicated to the identification of charged hadrons. It...
The NA62 experiment is designed to measure the extremely rare kaon decay $K^{+} \rightarrow \pi^{+} \nu \bar{\nu}$ at the CERN SPS. This decay mode is highly sensitive to indirect effects of new physics at energy scales beyond the reach of current accelerators, and its branching ratio is predicted with high precision by the Standard Model to be below $10^{-10}$. One of the main experimental...
The RICH detector of the CLAS12 experiment at Jefferson Lab has been designated to separate kaons from pions and protons in the momentum range between 3 and 8 GeV/c.
The detector geometry is based on an innovative hybrid optics design, with Cherenkov photons that can be detected either directly or after one or more reflections on a mirror system.
Its main components are: i) high...
The GlueX experiment is located in experimental Hall D at Jefferson Lab (JLab) and provides a unique capability to search for hybrid mesons in high-energy photoproduction, utilizing a ~9 GeV linearly polarized photon beam. Since 2020 a Detector of Internally Reflected Cherenkov light (DIRC) has been in use at GlueX, utilizing components from the decommissioned BaBar DIRC. In this...
