Tests of the BURLE 85011 micro-channel plate PMT as the detector of Cherenkov photons

Using aerogel as radiator and the BURLE 85011 multianode microchannel plate PMT for photon detection, a proximity focusing Cherenkov ring imaging detector has been constructed and tested in the KEK /spl pi/2 beam. The aim was to experimentally study the performance of the photon detector, in particular its ability to efficiently detect single photons.
