Charged particles accelerated by wake fields in a dielectric resonator with exciting electron bunch channel

Abstract

We have studied the acceleration of electrons by wake fields excited in a resonator by a train of electron bunches. The resonator comprised a cylindrical metal waveguide section, containing a dielectric sleeve with a vacuum channel and ends closed by metal walls. Expressions describing the wake field excited by uniformly moving exciting electron bunches have been derived. The self-consistent process of resonator excitation by a train of charged bunches and the particle acceleration in the excited wake field has been numerically simulated.
