  1. 4. The use of saturated fluorocarbon fluids in high energy physics
    Dr Gregory Hallewell (Centre de Physique des Particules de Marseille)

    Technological aspects of Cherenkov detectors
    Oral presentation
    The excellent dielectric properties of saturated (CnF(2n+2)) fluorocarbons have allowed their use in direct immersion liquid cooling of electronics, for example in the Cray series supercomputers. They have also found extensive use as heat transfer media in vapour phase soldering. Their high density and optical transparency led to the suggestion by Seguinot and Ypsilantis for their use as...

  2. 53. The ALICE HMPID Detector Control system, its evolution towards an expert and adaptative system
    Dr Giacinto de Cataldo (INFN sez. Bari Italy and CERN CH)

    Technological aspects of Cherenkov detectors
    Oral presentation
    The High Momentum Particle Identification Detector (HMPID) is a proximity focusing ring imaging Cherenkov (RICH) for charged hadrons identification at momenta 1< p < 3 GeV/c for pi and K and 1< p < 5 GeV/c for p. The HMPID uses liquid C6F14 as radiator medium. The detection of the Cherenkov UV photons is carried out via CsI coated photocathodes and MWPCs. To ensure a stable particle...

    Technological aspects of Cherenkov detectors
    Oral presentation
    Hadron identification in the LHCb experiment is performed by Ring Imaging Cherenkov (RICH) detectors. The system is composed by two RICH detectors, three radiators, imaging optics and 484 Hybrid Photon Detectors (HPDs). The refractive index of the radiators (16 aerogel tiles, C4F10 and CF4) is calibrated using saturated (beta=1) tracks and expected changes due to atmospheric pressure...

  4. 70. Mirrors alignment control at Compass RICH-1 detector
    M. Lukas Steiger (Technical University of Liberec)

    Technological aspects of Cherenkov detectors
    Oral presentation
    The COMPASS RICH-1 detector has been using two reflecting segmented spherical mirrors, constructed from 68 hexagonal and 48 pentagonal individual mirrors. All mirrors have three degrees of freedom per segment, i.e., piston, tip, and tilt. The influence of external vibrations, pressure and temperature fluctuation can change alignment of individual mirrors with respect to optimal spherical...
