Recent results from the DELPHI barrel ring imaging Cherenkov counter

Recent Results From Crystal Barrel

The Crystal Barrel experiment has continued its program to clarify the nature of low mass resonances. Results from high multiplicity nal states, nal states containing kaons (partly rendered possible by a hardware upgrade-a silicon microstrip detector), and annihilation in ight (in which the rest frame energy is extended up to 2.4 GeV) are presented. In addition, several tests of chiral perturba...

The 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...

The current progress of the ALICE Ring Imaging Cherenkov Detector

Recently, the last two modules (out of seven) of the ALICE High Momentum Particle Identification detector (HMPID) were assembled and tested. The full detector, after a precommissioning phase, has been installed in the experimental area, inside the ALICE solenoid, at the end of September 2006. In this paper we review the status of the ALICE/HMPID project and we present a summary of the series pr...
