Design and expected performance of the BTeV RICH

The BTeV experiment is a b-physics experiment designed to conduct precision tests of the CKM description of CP violation and study rare processes involving bottom and charm hadrons. The experiment will be located in the C0 interaction region at the Fermilab Tevatron, and is intended to begin data-taking around 2007–2008. One of the most important elements of the BTeV spectrometer is the ring-imaging Cherenkov detector (RICH) which is used for particle identification. In this article we describe the BTeV RICH and present its expected performance.
