Detection of internally reflected Cherenkov light, results from the BELLE DIRC prototype
The DIRC (Detector of Internally Reflected Cherenkov light) is a new type of ring imaging Cherenkov detector which utilizes precisely machined quartz bars as Cherenkov radiators. Bar quality is determined by both laser and cosmic ray measurements. The Cherenkov photons are transported several meters along the bar until they reach the detector cavity where they are proximity focussed on an array...
متن کاملThe Ring Imaging Cherenkov Detectors for LHCb
The success of the LHCb experiment depends heavily on particle identification over the momentum range 2−100 GeV/c. To meet this challenge, LHCb uses a Ring Imaging Cherenkov (RICH) system composed of two detectors with three radiators. RICH1 has both aerogel and gas (C4F10) radiators, while RICH2 has only a gas (CF4) radiator. The design of RICH1 is almost complete, whereas RICH2 has been const...

Some conceptual design features of the total internally re ecting, imaging Cherenkov counter (DIRC) are described. Limits of the DIRC approach to particle identi cation, and a few features of alternative DIRC designs, are brie y explored. Invited talk presented at the Third International Workshop on Ring Imaging Cherenkov Detectors Ein-Gedi, Dead Sea, Israel November 15-20, 1998 Work supported ...
متن کاملOptical Properties of the Dirc Fused Silica Cherenkov Radiator
The DIRC detector is successfully operating as the hadronic particle identification system for the BaBar experiment at SLAC. The production of its Cherenkov radiator required much effort in practice, both in manufacture and conception, which in turn required a large number of R&D measurements. One of the major outcomes of this R&D work was an understanding of methods to select radiation hard an...
متن کاملNovel Cherenkov photon detectors
Gaseous detectors using multiple gas electron multiplier (GEM) electrodes permit to attain large amplification factors with a strong suppression of photon and ion-mediated feedback. With the first GEM in a cascade coated with a photosensitive layer, they provide efficient and fast single photon detection, with excellent position resolution. General performances of CsI-coated multi-GEM detectors...
