Description

A 50x50 cm2 RICH detector was tested with hadron beams of 200 GeV/c to determine the resolution and efficiency of the system. Single photon detection has been achieved with a multistep avalanche chamber in conjunction with a CCD camera equipped with a 35 mm f/1.4 lens coupled to a two stage image intensifier. The results show that for the number of photons detected with the present setup and the geometry used in proximity focusing a standard deviation of 7.5 mrad per event has been achieved for the reconstruction of the Cherenkov angle.
