论文摘要
我们介绍了在气体射流处产生相对的热等离子体的第一种方法 - 可访问的密度。使用完全动力学的模拟和理论，我们证明了由两个激光脉冲在应用磁场中驱动的直接激光加速度的两个阶段可以将显着的等离子体体积加热到多MEV平均能量。最高的摩氏特征是2D相互作用，在相互作用之后持续存在，其中大多数电子在首次在光学诊断的方向下实现了实验性访问大量相关的高能密度等离子体。
We introduce the first approach to volumetrically generate relativistically thermal plasma at gas-jet--accessible density. Using fully kinetic simulations and theory, we demonstrate that two stages of direct laser acceleration driven by two laser pulses in an applied magnetic field can heat a significant plasma volume to multi-MeV average energy. The highest-momentum feature is 2D-isotropic, persists after the interaction, and includes the majority of electrons, enabling experimental access to bulk-relativistic, high-energy-density plasma in an optically diagnosable regime for the first time.
