Numerical and analytical study of the electron heating by plasma waves
Abstract:
Electron heating and acceleration by wakefield caused by the laser pulse is studied with help of the space nonuniform Fokker-Planck equation. Relativistic intense laser pulse propagates in a plasma with prescribed values of density and quasistationary plasma wave spectrum. Electron heating is considered in frame of plasma-wave interaction on the base of quasilinear theory. Previous to front, the extending distribution function tails is building-up in the course of impulse propagation. Numerical solution has the coincident asymptotic form with the obtained analytical solution. The paper proceeds and evelops the previous work on the subject.
