The Barrel Ring Imaging CHerenkov (BRICH) detector as mentioned in this paper is a photoensitive gas-filled drift chamber where the photoelectrons drift to a MWPC of special construction.
Abstract
A short explanation is given of the Barrel Ring Imaging CHerenkov (BRICH) detector and its performance. We discuss in brief some of the requirements to run this detector. Special attention is paid to the functioning of the Cherenkov photon detector — a photosensitive gas-filled drift chamber where the photoelectrons drift to a MWPC of special construction. We illustrate the BRICH performance with some preliminary results.

A historical survey of ring imaging Cherenkov counters

TL;DR: Ring Imaging Cherenkov (RICH) counters as discussed by the authors have been used for particle identification since 1977, and have been classified into three groups, each developed over the last sixteen years, but based on different techniques and readout methods.

Lifetimes of charm and beauty hadrons

TL;DR: In this paper, the lifetimes of all weakly decaying singly charmed hadrons have been measured, some with an accuracy of a few percent, and the difference in the shortest lifetime and the longest one is given by a factor of close to ten, while the experimental status of beauty lifetimes has still reached a new level of quality and is now better than 5% for the commoner states.

Photo-ionization and Cherenkov ring imaging

TL;DR: In this article, the photo-ionization process in gases and single photon pulse counting in multi-wire proportional chambers (MWPC) was investigated and shown to be possible with about 50% quantum efficiency for photons above 9.5 eV.
