Multiplexed focusing Cerenkov counter

An optical system replacing the usual diaphragm is described, which can extend the angular and velocity acceptance of focusing Cerenkov counters. The use of such counters is therefore no longer limited to nearly parallel beams and is possible in many experimental configurations. (5 refs)

Čerenkov counters for particle identification at high energies

The general design features of the threshold, differential, and DISC types of gas Cherenkov counters are discussed in the context of their application as particle detectors at high energies. (10 refs)

A spot-focusing Cerenkov counter for the detection of multiparticle events at high energies

A new type of Cerenkov counter is described for the detection of multiparticle events emitted from a small-size production target. The detector focuses the Cerenkov light produced by a particle of a given velocity beta /sub 0/ to a spot image. The counter produces an output of the angular coordinates and, for particles having gamma values within a given range, provides a determination of the velocity of each detected particle. The general principles of the design of this type of detector are presented, together with the computed results for a particular example. (7 refs)
