CLEO III, a detector to measure rare B decays and CP violation

The symmetric e+e− collider CESR is undergoing a series of upgrades allowing for luminosities in excess of 2 × 1033 cm−2s−1. The most important goals of the upgrade are precision measurement of standard model parameters Vcb, Vub, VtdVts, fDs, and searching for CP violation and standard model violations in rare B decays. A new detector upgrade, called CLEO III, has started which includes a new silicon-wire drift chamber tracking system and a Ring Imaging Cherenkov Detector, RICH, using a LiF radiator and CH4-TEA gas based photon detector.
