Abstract
Calorimeters using high pressure gas as active medium are now being co nsidered as candidates for the forward region of detectors at high lum inosity colliders. A parallel plate electromagnetic calorimeter and a high pressure test vessel have been used to study and compare the resp onse of Ar+CH4, Ar+CF4, Ar+C2H6, Xe+CH4 and Xe+CF4 gas mixtures to 50 GeV electrons and to alpha particles from an Am-241 source. Results on the energy resolution, the electron drift velocity, and the collected charge as a function of electric field and gas pressure for the diffe rent gas mixtures are compared.
