Jitter of XFEL signals due to the disorder of pump-probe time delay is explored theoretically. Two basically different methods are applied: statistical mechanics and dimensional analysis. Although completely different, these two approaches suggest the same method to suppress jitter generated perturbations. The method which is proposed here is easily applicable and requires no computational effort.

XFEL实验中泵浦探针时间延迟的抖动：如何消除？

理论上研究了由于泵浦探针时间延迟的混乱而引起的XFEL信号的抖动。应用了两种基本不同的方法：统计力学和尺寸分析。尽管完全不同，但这两种方法建议使用相同的方法来抑制抖动产生的扰动。这里提出的方法是容易应用的并且不需要计算工作。
