Abstract

The aim of the investigation was to study the increase of sensitivity of ion chambers operated in the internal gas multiplication voltage range, to specify operating conditions and establish limitations. Amplification factors were determined for a proportional-counter-like device filled with various pure gases and gas mixtures, at different voltages and pressures. There is overall agreement with theoretical predictions for the majority of fillings, except for pure nitrogen and pure argon. The suppression of the gas gain becomes noticeable at exposure rates of about 250 nA/kg and becomes drastic st about 4 µA/kg.
