Abstract :
Characteristics of the gas ionisation electromagnetic (EM) calorimeters with 1.5 and 3 mm lead absorbers has been studied using 6–30 GeV electron beams of the IHEP accelerator. The calorimeters were filled with heavy freon C3F8. The results of the electronics noise measurements are presented. The dependencies of the average signal and the energy resolution on the beam energy, gas pressure and high voltage are discussed.
