Particle identification by Cherenkov and transition radiation
Abstract
The Cherenkov counter has a role as a particle identifier for velocities which are too high for Time-of-Flight to be used, and too low for transition radiation detectors to give a useable signal. In beam lines the compensated differential counter is capable of giving the best resolution, but at high momenta the restriction on the spread of particle directions gives unacceptable limits on the beam acceptance. The transition radiation detectors being developed to identify hadrons at relatively low momentum do not have this restriction and might be used instead. For particles produced in an interaction, the ring imaging type of Cherenkov should give the best coverage for multiparticle events, but a threshold counter is much simpler, cheaper and faster where it can give adequate separation. Again at high values of ..gamma.. the resolution of Cherenkov counters will fail and some form of transition radiation detector will be necessary.
