Title: Betatron radiation from electron beams in plasma focusing channels

Abstract

Spontaneous radiation emitted from an electron undergoing betatron motion is a plasma focusing channel is analyzed and applications to plasma wakefield accelerator experiments and to the ion channel laser (ICL) are discussed. Important similarities and differences between a free electron laser (FEL) and in an ICL are delineated. It is shown that the frequency of spontaneous radiation is a strong function of the betatron strength parameter a{sub {beta}}, which plays a similar role to that of the wiggler strength parameter in a conventional FEL. For a{sub {beta}} {approx_gt} 1, radiation is emitted in numerous harmonics. Furthermore, a{sub {beta}} is proportional to the amplitude of the betatron orbit, which varies for every electron in the beam. This places serious limits on the possibility of realizing an ICL.
