| Summary: | The electron storage ring CESR at Cornell University is presently undergoing a major upgrade together with its B-physics detector CLEO. Improved focusing and superconducting cavities will increase the luminosity of the collider to more than 2 x 10(33) cm(2) s(-1). To accommodate the necessary accelerator elements the tracking region of CLEO has to be rebuilt. The new tracking system consists of a four-layer silicon vertex detector and a large volume drift chamber, which also provides dE/dx particle identification information. The CLEO III upgrade also includes a new particle identification system which allows full exploitation of the possibilities provided by the upgraded accelerator. This PID system is a proximity focusing RICH with lithium fluoride radiators and multi-wire chambers filled with a methane/triethylamine mixture to detect UV Cherenkov photons. Installation of the new detector elements in the CLEO detector is taking place during summer 1999. (C) 2000 Elsevier Science B.V. All rights reserved. |
