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. Keywords: Current modulation; Intense relativistic electron beam; High power radio frequency amplifier.
