Simulations of transitional self-modulated laser wakefield acceleration driven by laser pulses of a few terawatts are discussed, comparing a downramp-based injection regime with an ionization injection regime. We demonstrate that a configuration using an gas target and a laser pulse of ∼75 with ∼2 peak power is a good alternative as a high repetition rate system that produces electrons of many tens of MeV, pC charge, and emittance of the order of 1 mm mrad.
我们讨论了由几太瓦激光脉冲驱动的过渡自调制激光尾流加速的模拟，比较了基于下斜坡注入的方式和离化注入的方式。我们证明，使用气体靶和峰值功率约为 2 的激光脉冲（持续时间约为 75 ）的配置是一种很好的替代方案，作为一种高重复率系统，可以产生数十 MeV 的电子、皮库电荷量和亚毫米毫拉德量级的发射度。
