Secondary emission magnetron injection gun for linac

Abstract

The experimental research results for operation of the cold cathode magnetron injection gun in the linear traveling wave accelerator are described. The mechanism of the gun operation is connected with the current secondary electronic increase and the establishment of a self-supported secondary emission. The comparison of the beam passage conditions for a thermionic gun points on the fact, that the characteristics of the magnetron gun are acceptable for the purposes of injection in the rf accelerator.

Secondary emission magnetron injection gun in long pulse mode

“…It is based on a new principle: selfsupported secondary emission in crossed fields. The gun may be used as injector in electron linacs [2] and radiofrequency power sources [3][4][5][6] for accelerators.…”

Pulse modulators for feeding powerful microwave devices based on magnetron guns with secondary-emission cathodes

“…The interest in these electron sources is due to a number of advantages (long lifetime, high current density, relative simplicity in design, etc.) enabling one to use them as electron sources when creating high-power long-term) microwave devices [1,[8][9][10]. The present paper is devoted to the problems of creating pulse modulators with a complete discharge of the formation line for feeding microwave devices, using magnetron guns with cold secondary-emission cathodes as the basis.…”
