Effect of a pulsating electric field on ECR heating in the CERA-RX(C) X-ray generator

3D particle-in-cell plasma simulations for the field configurations implemented in the CERA-RX(C) ECR X-ray generator (2.45 GHz) have been conducted. Dependences of the energy spectra of electrons incident on the target electrode on the amplitude and frequency of pulsations of the electric field in a megahertz range are derived. The simulation data are compared with the results of the full-scale experiment. © 2016, Pleiades Publishing, Ltd.
