采用三维粒子模拟方法研究了强激光脉冲作用下辐射压力驱动的小固体密度等离子体加速和压缩过程。研究发现，短脉冲激光多次冲击小半球壳靶，可以产生一个长寿命的微小准中性单能等离子体束团，具有很高的能量密度。
Three-dimensional particle-in-cell simulation is used to investigate radiation-pressure driven acceleration and compression of small solid-density plasma by intense laser pulses. It is found that multiple impacts by presently available short-pulse lasers on a small hemispheric shell target can create a long-living tiny quasineutral monoenergetic plasma bunch of very high energy density.
