Abstract

We investigate collisionless shock acceleration of spin-polarized

He for laser pulses with normalized vector potentials in the range

a0=100−200

. The setup utilized in the 2D-particle-in-cell simulations consists of a solid carbon foil that is placed in front of the main Helium target. The foil is heated by the laser pulse and shields the Helium from the highly oscillating fields. In turn, a shock wave with more homogeneous fields is induced, leading to highly polarized ion beams. We observe that the inclusion of radiation reaction into our simulations leads to a higher beam charge without affecting the polarization degree to a significant extent.

高激光强度下来自固体-气体复合靶的自旋偏振 3He 冲击波

我们研究了归一化矢量势在 a0=100-200 范围内的激光脉冲对自旋极化 3He 的无碰撞冲击加速。二维粒子池内模拟中使用的装置包括放置在主氦气靶前的固体碳箔。碳箔被激光脉冲加热，屏蔽了氦的高振荡场。反过来，具有更均匀场的冲击波被诱发，从而产生高度极化的离子束。我们观察到，在模拟中加入辐射反应会导致更高的离子束电荷量，而不会对极化程度产生重大影响。

期刊介绍： Plasma Physics and Controlled Fusion covers all aspects of the physics of hot, highly ionised plasmas. This includes results of current experimental and theoretical research on all aspects of the physics of high-temperature plasmas and of controlled nuclear fusion, including the basic phenomena in highly-ionised gases in the laboratory, in the ionosphere and in space, in magnetic-confinement and inertial-confinement fusion as well as related diagnostic methods. Papers with a technological emphasis, for example in such topics as plasma control, fusion technology and diagnostics, are welcomed when the plasma physics is an integral part of the paper or when the technology is unique to plasma applications or new to the field of plasma physics. Papers on dusty plasma physics are welcome when there is a clear relevance to fusion.
