ELECTRON ACCELERATION DUE TO THE SYNERGETIC EFFECT OF DC ELECTRIC-FIELD AND WAVES

The combined influence of two types of fast waves and a de electric he ld which is aligned with the ambient magnetic held on electron distrib ution function is studied by numerical simulations. A quasi-linear ope rator models the electron Landau damping of any plasma eigenmodes: kin etic Alfven, whistler;, and lower hybrid waves. For the description of weak collisional plasma processes, the 2D nonlinear kinetic Fokker-Pl anck equation is used. The distribution function structure, the electr on current induced by waves, and the quantitative and qualitative aspe cts of runaway production are analyzed.
