Abstract :
A fast RICH will act as a hadron blind trigger device in the high-resolution di-electron spectrometer HADES. The goal is to identify e+e− pairs from meson decays produced in hadron and heavy-ion induced collisions at a few GeV/nucleon incident energy. Concept and expected performance of the RICH utilizing a C4F10-radiator and a gaseous photon detector with CsI-converter are discussed. Preliminary results of a first in-beam measurement are presented.
