N. Leros et al., AN OPTICAL DISCRIMINATOR FOR HYPERON PHYSICS, Nuclear instruments & methods in physics research. Section A, Accelerators, spectrometers, detectors and associated equipment, 387(1-2), 1997, pp. 88-91
The use of an optical discriminator for fast hyperon selection has bee
n investigated by the RD30 Collaboration. A realistic Monte-Carlo simu
lation of this device based on the detection of the Cherenkov light pr
oduced in a thin crystal shows quite promising performances. Such a di
scriminator has been built and the first results obtained in a pion be
am will be presented.
