摘要

En 中文

我们研究了激光辐照等离子体中发射伽马射线呈现单瓣与双瓣角分布的机制，重点关注直接激光加速（DLA）如何塑造发射谱形。通过测试粒子计算，我们发现DLA的效率起着核心作用。在低效DLA区域，电子在单个激光周期内迅速获得和损失能量，导致发射谱形呈双瓣分布，且受激光场强烈影响。相比之下，在高效DLA区域，电子在多个激光周期内稳定积累能量，达到更高能量并发射能量高出数个量级。这种发射具有强准直性，并形成由等离子体中准静态方位角磁场主导的单瓣谱形。粒子网格（PIC）模拟表明，低密度靶为部分电子进入高效DLA区域创造了有利条件。这些电子能够主导发射，使整体谱形从双瓣转变为单瓣，尽管低效DLA电子仍然存在。这些发现为优化激光驱动伽马射线源以实现高强、准直性好的束流应用提供了重要见解。
