Generation of high-power electron beams in magnetron guns with cold secondary-emission cathodes

Abstract

The generation of powerful electron beams in a single magnetron gun and in a set of magnetron guns with cold secondary-emission cathodes is studied. The possibility of generating tubular electron beams of current 50–100 A, particle energy 30–100 kV, and pulse power 1–5 MW is shown. Such beams can be used as electron sources in the technology of accelerators, as well as in ordinary and multibeam high-power microwave devices.
