Stimulated Backscattering from Relativistic Unmagnetized Electron Beams

Abstract

Analysis of stimulated scattering of a high frequency incident pump wave from an unmagnetized relativistic electron beam is presented. The backscattered radiation frequency can be enhanced by the factor 4 gamma squared over the incident pump frequency where gamma omicron is the relativistic factor of omicron the electron beam. The linear growth rates associated with the wave-wave and wave-particle modes of scattering are examined for a number of different pump amplitude regimes. Estimates for the scattering efficiency are presented for the wave-wave scattering process.
