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...

The Ring Imaging Cherenkov detector ( RICH ) of the AMS experiment

The Alpha Magnetic Spectrometer (AMS) experiment to be installed on the International Space Station (ISS) will be equipped with a proximity focusing Ring Imaging Cherenkov (RICH) detector for measuring the electric charge and velocity of the charged cosmic particles. A RICH prototype consisting of 96 photomultiplier units, including a piece of the conical reflector, was built and its performanc...

LHC-B Ring Imaging Cherenkov Detector

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...

ICFA Instrumentation Bulletin BEAM TESTS OF THE CLEO III LIF-TEA RING IMAGING CHERENKOV DETECTOR

We present preliminary results from a test beam run of CLEO III RICH modules. The system consists of LiF radiators and multiwire proportional chambers containing a mixture of CH4 and TEA gases. The radiators were both at and \sawtooth." The data were taken in a beam dump at Fermilab. We will discuss the chamber stability, electronics, the number of photons observed for both radiators, the angul...
