Abstract

Summary form only given, as follows. The magnicon is a microwave amplifier in which the beam is modulated by means of its circular deflection. Presented in this report is a frequency doubling amplifier developed as a prototype of the microwave energy source for linear colliders. The magnicon is driven by a beam with a power of up to 100 MW and a microperveance of 0.83, the source of which is a thermionic electron gun with a very high convergence (up to 2000:1 in area). During the investigation the following results were obtained: a power of 30 MW, an efficiency of 35%, and a gain of 55 dB. This paper presents the tube design, problems faced and overcome during the investigation, and possible methods of further improving the device.
