Abstract
In this article, the experimental and theoretical data are presented which demonstrate the possibility of controlling the specimen surface temperature during irradiation with a submillisecond electron beam produced by a plasma-cathode electron source. The specimen surface temperature is controlled by modulating the beam current via appropriate short-time variations in the emission plasma parameters. The temperature ripple factor, measuring less than 5% in our experiments, is defined as the product of the specimen surface temperature and the discretization degree of the beam current and its pulse duration. The efficiency of the method of temperature control is confirmed by numerical simulations. The proposed method opens the way to new applications of plasma-cathode electron sources in science and technology.
