Net acceleration of high-energy electron beams by net inverses bremsstrahlung of a laser wave in isotropic turbulent plasma waves and a uniform magnetic field

Abstract

The net dc force (ponderomotive force) acting on a high-energy electron beam (⪢ 10 MeV) due to net inverse bremsstrahlung of a laser wave in isotropic turbulent plasma waves and a uniform magnetic field is calculated by using quantum kinetics. It is shown that the net force, averaged over the electron distribution, is independent of the beam energy spread, increases with the beam energy, and exceeds the oscillating Lorentz force of the laser wave when the electron energy is large.
