摘要: Spontaneous radiation emitted from relativistic electrons undergoing betatron motion in a plasma focusing channel is analyzed and application to wakefield accelerator experiments the ion laser (ICL) are discussed. Important similarities differences between free electron (FEL) an ICL delineated. It shown that frequency of spontaneous strong function strength parameter alpha-beta, which plays similar role wiggler conventional FEL. For alpha-beta > 1, numerous harmonics. Furthermore, proportional amplitude orbit, varies for every beam. The spectrum beam calculated by averaging single over distribution. This leads broadening spectrum, places serious limits on possibility realizing ICL.
