Dielectric wake-field generator

Abstract

Wake-fields excited in a dielectric media can be applied both for particle acceleration and for HF-power generation. In the present work theoretical and experimental investigations are presented on the generation of electromagnetic wake-fields in a dielectric tube by a sequence of relativistic electron bunches. The peaked high power obtained due to the coherent superposition of the wake-fields of the regular sequence of bunches and multi-mode operation has been investigated. Measurement of wake-field output power and beam electron energy losses were performed.
