G. Vanapeldoorn et al., PERFORMANCE OF THE BARREL RING IMAGING CHERENKOV COUNTER OF DELPHI, IEEE transactions on nuclear science, 41(4), 1994, pp. 866-870
The Barrel Ring Imaging Cherenkov detector of the DEL-PHI experiment a
t LEP provides particle identification by the detection of the radiati
on emitted in UV transparent perfluorocarbons. We will present the pri
nciples of the operation of the detector together with a discussion of
the automatized control of all the relevant physical parameters. The
observed performances of the detector are very close to their design v
alues.
