论文摘要
这是对在2019年在葡萄牙锡西姆布拉举行的2019 Cern Accelerator学校讲座后，在2019年CERN加速器学校讲座后，由激光脉冲或粒子梁驱动的等离子体尾矿中电子的加速度进行了简要回顾。总结了驱动因素及其强度参数与当前实验的操作参数之间的共同点（LWFA）（LWFA）和光束驱动的等离子体等离子体Wakefield加速度（PWFA）。引入了能量限制，包括激光器的去驱动和耗竭长度，以及光束驱动等离子体的变压器比率。引入了唤醒汉密尔顿的概念，并在相空间中鉴定出所得的粒子轨道，这说明了如何确定加速电子的峰值能量和能量传播。
This is brief review of acceleration of electrons in plasma wakefields driven by either intense laser pulses or particle beams following lectures at the 2019 CERN Accelerator School on plasma accelerators, held at Sesimbra, Portugal. The commonalities between drivers and their strength parameters and operating parameter regimes for current experiments in laser wakefield acceleration (LWFA) and beam driven plasma wakefield acceleration (PWFA) are summarized. Energy limitations are introduced, including the dephasing and depletion lengths for lasers, and the transformer ratio for beam driven plasmas. The concept of the wake Hamiltonian is introduced and the resulting particle orbits are identified in phase space, which illustrates how the peak energy and energy spread of accelerated electrons are determined.
