A Study of Pulse Shapes in a Parallel-Plate Ionization Chamber

Abstract

The general features of electron collection in a parallel‐plate ionization chamber are discussed with reference to the detection of single particles. If the particles come from the surface of one of the electrodes and end their paths within the chamber, the pulses obtained by electron collection can give information regarding the energy of the particles, their range, the angle between the tracks and the field of the chamber, and their ``range‐energy'' function. Electronic and photographic measurements are described which confirm the expected form of the pulses and indicate the quantitative possibilities of this method of detection.
