Effets causés par la collection des électrons dans une chambre d'ionisation cylindrique

Abstract

The effect of using electron collection in a cylindrical, pulse ionization chamber is analysed. Ionizing trajectories crossing the chamber from end to end and ideal conditions are assumed. The probability of observing pulses of a given amplitude is shown to depend on this amplitude. The resulting statistical distribution of pulse amplitudes to be expected under typical conditions of operation is calculated as an example, from Landau's theoretical distribution of energy losses.
