Plasma block acceleration under ultraintense laser pulse
-
摘要: 为了克服激光加速中强流离子束空间电荷效应对粒子输运的影响,提出一种利用两块不同密度的固体靶先后和一束强度约为1022 W/cm2、脉冲长度为5T(T为激光周期)的超强脉冲激光相互作用的方案,实现了中性等离子体块的加速。通过一维PIC数值模拟研究发现,在合适的参数下,加速后的电子与质子几乎以相同的速度共同飞行长达60(为激光波长)的距离,其中质子与电子的能量分别为GeV和100 MeV量级。

Abstract: In order to overcome the space charge influence over the transport of the high-current particle beams in laser acceleration, we propose a new scheme to realize the acceleration of a neutral plasma block. It is carried out by injecting an ultraintense laser pulse with intensity about 1022 W/cm2 and pulse duration about 5T (T is laser period) upon two thin solid-density plasma blocks. By optimizing the plasma parameters, we have obtained an accelerated plasma block, which is almost neutral and propagates for a quite long distance in the space. The ion and electron energies are of GeV and 100 MeV magnitude respectively. 期刊类型引用(2)
