Trieste workshop workshop puts a RICH variety on show

摘要

Ring imaging Cherenkov (RICH) counters provide a unique tool to identify charged particles by measuring their velocity, even when it differs from the velocity of light by only one part in 10 million. The devices detect the visible and UV photons emitted through the Cherenkov effect, measuring the angle of the Cherenkov radiation with an imaging technique, and hence the velocity. This method offers the possibility of measuring particle velocity in domains where others fail, opening the way to particle identification over a wide range of particle momenta. In the current era of high-resolution and high-precision experiments, the domain of applications is becoming even larger, and more challenging requirements for the design of new detectors are arising.
