“…Newer generation devices, like the RICHes in LHCb [44][45][46] and ALICE [47][48][49], are just starting operation, and at this conference first results will be presented. There are two more RICH projects which were cancelled due to internal politics in the USA; we should have been able to see first results from the BTeV [50] and CKM [13,14] RICHes.…”

“…Gaseous photodetectors with opaque CsI photocathodes and readout using multiwire chambers are successfully used in the so called proximity focused RICH detectors in experiments at CERN [10,51], GSI [52], and BNL [10]. Figure 1 shows the schematic diagram of such RICH detector [51]: the Cherenkov radiation emitted in the liquid radiator goes through the quartz window to the multiwire chamber in which it is registered using the CsI photocathode deposited on the cathode areas. The chamber is flushed with pure methane, which provides, first, minimal photoelectron backscattering effect (see Section 2), and second, high (about 5 × 10 4 ) gas gain.…”

“…Thus, "good" gases for minimization of the effect of photoelectron backscattering are CF 4 and CH 4 , "moderately good" gases are C 2 H 6 , i-C 4 H 10 , Ar + N 2 , and Ar + CH 4 , and "bad" gases are pure noble gases and He-based mixtures. It is this property that was taken into account when CF 4 and CH 4 were chosen as the gases for photodetectors with CsI photocathode for RICH detectors in the experiments PHENIX [35] and ALICE [51], respectively.…”

Remarkable properties of gas photodetectors make them attractive for application in high energy physics, astrophysics, and medical imaging. This review presents the results of research and development of gaseous photodetectors with solid photocathodes (GPDs). In particular, efficient photocathodes for the ultraviolet (mainly CsI) and the visible ranges, including photocathodes with protective dielectric nanofilms, are described. Some problems of the physics of gaseous photodetectors and photocathodes are considered: photoelectron backscattering in gas, photoemission amplification in an electric field, photoelectron transport through nanofilms, protective properties of nanofilms, and photon and ion feedback. A separate section is devoted to GPDs based on gas electron multipliers (GEMs), including sealed GPDs and cryogenic two-phase avalanche detectors with CsI photocathodes.

Special features and parameters of detectors, front end electronics, and trigger electronics of the ALICE setup, which is intended for investigations of ultrarelativistic nucleon-nucleon collisions at the LHC and for studies of heavy ion collisions, starting from protons to several types of ions, which have 5.5 TeV/nucleon energy in the center of mass, are described. One of the first collisions of lead ions was recorded by the ALICE detector
