Abstract

High conversion efficiency of electron beam energy to rf energy can be achieved in two-beam accelerators using reacceleration of the bunched drive beam. To study issues with these designs we are planning a demonstration in which a modulated beam´s energy is boosted as it passes through induction accelerator cells. For this experiment we will use the front end of the Choppertron to modulate a 5 MeV electron beam at 11.4 GHz. We have now tested the 5-MeV Choppertron and are reporting on the results. For the reacceleration experiment we plan to use three stages of rf power extraction interspersed with two stages of reacceleration
