After ten years of R&D activities, an array of seven proximity focusing RICH modules is being built to identify π-K in the range 1 < p < 2.7 GeV/c and K-p in the range 1.5 < p < 5 GeV/c in the ALICE experiment at LHC. This device, named High Momentum Particle Identification Detector (HMPID), with a total active area of 11 m2, represents the largest scale application of MWPCs with high Quantum Efficiency (QE) CsI segmented photo-cathodes for the Cherenkov photon conversion. An overview of the RICH layout, the technique of photocathode production, the front-end (FE) and readout (R/O) electronics and finally the detector control system (DCS), are presented.

Abstract
After ten years of R&D activities, an array of seven proximity focusing RICH modules is being built to identify π-K in the range 1 < p < 2.7 GeV/c and K-p in the range 1.5 < p < 5 GeV/c in the ALICE experiment at LHC. This device, named High Momentum Particle Identification Detector (HMPID), with a total active area of 11 m2, represents the largest scale application of MWPCs with high Quantum Efficiency (QE) CsI segmented photo-cathodes for the Cherenkov photon conversion. An overview of the RICH layout, the technique of photocathode production, the front-end (FE) and readout (R/O) electronics and finally the detector control system (DCS), are presented.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
