✦ Synopsis

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 C 3 F 8 :

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.
