Modulation of an intense beam by an external microwave source: Theory and simulation
Abstract
A time dependent, fully electromagnetic particle code is used to simulate the current modulation in an intense relativistic electron beam (IREB) by an external RF source. It is shown that the intense beam may serve as a power amplifier with good phase stability, as suggested in earlier experiments. Increase in beam bunching by the dc space charge is demonstrated with a simple analytical model.
