Research on electron acceleration in interaction of intense laser and magnetized plasma by ponderomotive force

摘要

Electron acceleration in intense laser and magnetized plasma interaction by ponderomotive force has been researched. The results are shown that, under the influence of ponderomotive force, electron give rise to transverse oscillation and obtain high energy gain, moreover, the resonance by self-generated magnetic filed enforce ponderomotive force and further accelerate electron, lead to higher energy gain. At last, electron energy trend to a steady value, and the high energy electron would be automatic ejected by the ponderomotive force. The present scheme, it can avoid making use of additional extractor of acquiring high energy electron, which may provide useful physical support for novel design of table accelerator.
