摘要:

我们报告的空间和时间分辨的测量所产生的磁场拍瓦激光固体相互作用的高空间分辨率,使用光学偏振。极化测量映射兆高斯磁场剖面所产生的快速电子流在目标的后方。在50 $μ$ m厚的铝靶的后部的磁场表现出明显的和明确的电子束偏转的特征。这些结果证实了混合动力模拟。

英文摘要:

We report spatially and temporally resolved measurements of magnetic fields generated by petawatt laser-solid interactions with high spatial resolution, using optical polarimetry. The polarimetric measurements map the megagauss magnetic field profiles generated by the fast electron currents at the target rear. The magnetic fields at the rear of a 50 $μ$m thick aluminum target exhibit distinct and unambiguous signatures of electron beam filamentation. These results are corroborated by hybrid simulations.
