Synchrotron-Betatron Parametric Instability in Free-Electron Lasers

Abstract

Analysis of the synchrotron betatron coupling in a free electron laser indicates that the particle motion is susceptible to an instability which is of a fundamentally different physical character to those examined previously. The domain of this instability, which is of a parametric type and causes an exponential growth of the betatron amplitude, is identified and the growth rate therein determined. Keywords: Synchrotron-Betatron coupling; Parametric instability. (JHD)
