Construction and Performance of the BABAR-DIRC

Test of a Large Scale Prototype of the DIRC, a Cerenkov Imaging Detector based on Total Internal Reflection for BABAR at PEP-II*

The principles of the DIRC ring imaging Cerenkov technique are brie y explained and its choice for the BABAR detector particle identi cation system is motivated. A large scale prototype of the DIRC for the BABAR experiment is then described. Details of the design of this prototype and its test in a hadronic particle beam at the CERN-PS are presented, and results from various prototype and test ...

DIRC for a Higher Luminosity B Factory

The Dirc, a novel type of Cherenkov ring imaging device, is the primary hadronic particle identification system for the BABAR detector at the asymmetric B-factory Pep-II at SLAC. It is based on total internal reflection and uses long, rectangular bars made from synthetic fused silica as Cherenkov radiators and light guides. BABAR began taking data with colliding beams in late spring 1999. This ...

DIRC , a Newt Type of Particle Identification System for BABAR *

The DIRC, a new type of Cherenkov imaging device, has been selected as the primary particle identification system for the BABAR detector at the asymmetric B-factory, PEP-II. It is based on total internal reflection and uses long, rectangular barsmade from synthetic fused silica as Cherenkov radiators and light guides. In this paper, the principles of the DIRC ring imaging Cherenkov technique ar...
