Abstract
The characteristics of a gas ionization calorimeter with planar electr ode geometry have been studied in hadron and electron beams with momen ta from 19 to 50 GeV/c. The calorimeter was filled with a 95% Ar+5% CF 4 gas mixture. Absorbers were made of uranium and steel. The dependenc ies of energy resolution on gas pressure and absorber thickness are pr esented. The signal-to-noise and electron-to-hadron ratios are discuss ed.
