摘要

我们采用二维粒子池模拟，详细研究了沿平面 TNSA 靶的法线施加千特斯拉磁场对质子/离子截止能量的影响。对 (i) 正常入射单个激光脉冲和 (ii) 两个斜入射激光脉冲这两种情况进行了深入研究。结果表明，与正常入射的单激光脉冲和外部磁场（19MeV-24MeV）相比，结合外部磁场的双斜脉冲配置能使质子的截止能得到更强的增强（56MeV-75MeV）。因此，我们发现这种双斜激光脉冲与千特斯拉级外部磁场的组合在 TNSA 系统中加速质子/离子方面非常有效。

TNSA based proton acceleration by two oblique laser pulses in the presence of an axial magnetic field

We employ two-dimensional particle-in-cell simulations to examine, in detail, the effect of a kilo-Tesla magnetic field applied along the normal of a flat TNSA target on the cutoff energy of protons/ions. The two cases of (i) normally incident single laser pulse, and (ii) two obliquely incident laser pulses are thoroughly examined. It is shown that the two-oblique-pulse configuration combined with an external magnetic field results in a stronger enhancement (56 MeV–75 MeV) in the protons’ cutoff energies than the normally incident single laser pulse with an external magnetic field (19 MeV–24 MeV). This combination of two-oblique laser pulses along with a kilo-Tesla level external magnetic field is therefore found to be highly effective in accelerating protons/ions in the TNSA regime.
