Abstract :
A gas-RICH counter using a C4F10 radiator and pad readout has been developed. The good transmission of the optical elements together with a low noise level in the electronics results that on average 12 photoelectrons are detected per event for Z=1 particles with β∼1. The reconstructed Cherenkov angle has a resolution of 1.2 mrad. The RICH detector is an important part of a balloon borne experiment, CAPRICE, which measures the flux of antiprotons and positrons in the cosmic radiation.
