Laser-driven ion acceleration attracts large attention due to variety of applications. In order to enhance accelerated proton energy and flux, we investigate the influence of laser-driven relativistic magnetic reconnection on the ion acceleration processes. In this relativistic regime, the longitudinal electric field becomes significantly enhanced and plays an important role in charged particle acceleration. To realize conditions for the magnetic reconnection, two spatially separated relativistic laser beams were used. The results obtained show a shift of high energy proton propagation direction compare to that corresponding to the target normal sheath acceleration scenario as well as enhancement in proton flux.

磁靶中磁重联的影响增强离子能量和通量

激光驱动的离子加速技术因其用途广泛而备受关注。为了增强加速的质子能量和通量,我们研究了激光驱动的相对论磁重联对离子加速过程的影响。在这种相对论状态下,纵向电场显着增强,并在带电粒子加速中起重要作用。为了实现磁连接的条件,使用了两个空间上分离的相对论激光束。获得的结果表明,高能质子传播方向的位移与对应于目标法向鞘管加速情况的位移相比,质子通量有所提高。
