摘要：
The electron acceleration by a finite-amplitude solitary kinetic Alfven wave (SKAW) in the low-beta magnetized plasma is presented. It is found that the electron can be efficiently accelerated in both the parallel and the transverse directions of ambient magnetic field by a finite-amplitude SKAW up to several tenfold Alven velocity within the time 0.08 mu s. These results are greatly different from the case of the electron accelerated by a small-amplitude SKAW.
