Abstract

Currently, work is underway to create laser accelerators with beam focusing by plasma lenses. For effective focusing, it is necessary to investigate at which initiation of breakdown a discharge forms with a more uniform distribution of current density. Our studies have shown that the plasma distribution is uniform over a longer period of time, including the region of maximum current, if the discharge is initiated by an electron beam.

通过电子束放电研究等离子透镜

摘要

当前，正在进行通过等离子透镜聚焦光束的激光加速器的工作。为了有效聚焦，有必要研究在哪个击穿开始时会形成电流密度分布更均匀的放电。我们的研究表明，如果放电是由电子束引发的，则等离子体分布在更长的时间内是均匀的，包括最大电流区域。
