摘要：
It has been studied the quantitative aspects of a spectrum of kinetic Alfven waves (kAw) on the electron runaway production rate using the quasilinear and Fokker-Planck equations. It is shown that these modes enhance the runaway production rate via their Landau dissipation. It is found as a general feature that the enhancement is larger the weaker the background electric field, while for its absolute enhancement it is just the opposite. The enhancement of the runaway flux, in some cases, can be many orders of magnitude over the flux without waves. It has also been briefly discussed the consequences of this study for the amplification of planetary and stellar nonthermal emissions.
