Dirc , a New Type of Particle Identi cation System for BaBar
نویسنده
چکیده
The Dirc, a new type of Cherenkov imaging device, has been selected as the primary particle identi cation system for the BaBar detector at the asymmetric B-factory, Pep-II. It is based on total internal re ection and uses long, rectangular bars made from synthetic fused silica as Cherenkov radiators and light guides. In this paper, the principles of the Dirc ring imaging Cherenkov technique are explained and results from the prototype program are presented. The studies of the optical properties and radiation hardness of the quartz radiators are described, followed by a discussion of the detector design. Invited talk presented at the 5th International Workshop on B{Physics at Hadron Machines (Beauty'97) Santa Monica, California, USA October 13{17, 1997 Work supported by Department of Energy contract DE{AC03{76SF00515.
