螺旋线圈加速器是近年来激光驱动离子产生技术的一个新发展，它利用激光加速质子的宽发散角和宽带能谱特性产生超低发散角的准单能束。螺旋线圈加速器的模块化也提供了多阶段的诱人前景。在这里，我们显示，在原理证明的基础上，一个两阶段的配置，它允许光学调谐所选择的质子子束的能量。实验数据，粒子跟踪模拟证实，突出了精确控制束注入的重要性。在最佳时间延迟下实现了能量增益高达1.16 MeV（每级1.88 MeV，平均速率为1.11 GeV m− 1）的质子的有效后加速，这使得所选质子与加速纵向电场的同步在两级中都得以保持。
Helical coil accelerators are a recent development in laser-driven ion production, acting on the intrinsically wide divergence and broadband energy spectrum of laser-accelerated protons to deliver ultra-low divergence and quasi-monoenergetic beams. The modularity of helical coil accelerators also provides the attractive prospective of multi-staging. Here we show, on a proof-of-principle basis, a two-stage configuration which allows optical tuning of the energy of the selected proton beamlet. Experimental data, corroborated by particle tracing simulations, highlights the importance of controlling precisely the beam injection. Efficient post-acceleration of the protons with an energy gain up to∼ 16 MeV (∼ 8 MeV per stage, at an average rate of∼ 1 GeV m− 1) was achieved at an optimal time delay, which allows synchronisation of the selected protons with the accelerating longitudinal electric fields to be maintained through both stages.
