Salmon, J

The theory of high-frequency discharge in gas at low pressures is investigated, and the distribution function of electrons present in the gas is calculated. The evolution of the electronic density at the center of the discharge tube is studied in attributing to the secondary emission from the walls of the tube an essential role in electron multiplication. The conditions of starting are obtained. In the second part a detailed description of an ion source functioning at 96.5 Mc/s is given, and measurements made on it and the search for a theoretical explanation of certain of its properties are discussed. A brief analysis of different types of high-frequency ion sources is given, along with their utilization in corpuscular microscopy and particle accelerators. (J.S.R.)
