Direct-Action Accelerator Based on the Magnetron Gun With a Secondary-Emission Cathode and Iits Aplication in Radio-Technologies

Abstract

Studies have been made into the parameters of the electron beam produced by the accelerator with the secondary-emission cathode magnetron gun as the basis. The experiments were performed in the energy range between 80 and 150 keV with a specific beam power on the target from 5 to 20 J/cm2, this permitting the use of the beam for irradiating material surfaces. Plane metal samples were subjected to irradiation, and the radiated structure of material surface was examined by metallography methods. Experiments were made to measure the accelerator beam size in both decreasing and increasing magnetic fields; the possibility of irradiating inner and outer of cylindrical surfaces was demonstrated.
