摘要
磁压缩器为在 MeV-UED 中实现无抖动束压缩提供了一条极具吸引力的途径。与射频束流器相比，磁性压缩器不会带来额外的定时抖动，而且可以通过配置将上游能量波动引起的定时抖动降至最低。在这项工作中，我们讨论了为 MeV-UED 设计磁压缩器的原理。介绍了狗腿式压缩机从开始到结束的模拟。结果表明，在 100 fC 电荷下可以实现 11~fs 的束长，且发射率增长很小。
Magnetic compressors offer an attractive path toward jitter-free bunch
compression in MeV-UED. Compared with RF bunchers, magnetic compressors do not
introduce additional timing jitter and can be configured to minimize timing
jitter due to upstream energy fluctuation. In this work we discuss the
principles of designing magnetic compressors for MeV-UED. Start-to-end
simulation of a dogleg compressor is presented. Results show a bunch length of
11~fs can be achieved at 100 fC charge with small emittance growth.
