论文摘要
基于外部注射的梁驱动等离子体 - 沃克场加速有可能显着降低未来加速器的大小。加速过程的稳定性和质量在很大程度上取决于传入的束参数。当前轮廓的精确控制对于优化能量转移效率和保留能量扩散至关重要。在Flashforward的设施中，驾驶员 - Witness Bunch对成对的可调束长度和分离是通过分散部分中的一组准直仪生成的，这可以实现FS级别的控制纵向束轮廓。提出了准仪式及其调试的设计。
Beam-driven plasma-wakefield acceleration based on external injection has the potential to significantly reduce the size of future accelerators. Stability and quality of the acceleration process substantially depends on the incoming bunch parameters. Precise control of the current profile is essential for optimising energy-transfer efficiency and preserving energy spread. At the FLASHForward facility, driver--witness bunch pairs of adjustable bunch length and separation are generated by a set of collimators in a dispersive section, which enables fs-level control of the longitudinal bunch profile. The design of the collimator apparatus and its commissioning is presented.
