Time-resolved optical pump/X-ray probe experiments are often used to study structural dynamics. To ensure high temporal resolution, it is necessary to monitor the timing between the X-ray pulses and the laser pulses. The transition from a crystalline solid material to a disordered state in a non-thermal melting process can be used as a reliable timing monitor. We have performed a study of the non-thermal melting of InSb in single-shot mode, where we varied the sample temperature in order to determine the conditions required for repetitive melting. We show how experimental conditions affect the feasibility of such a timing tool.

重复的非热融化作为飞秒泵/探针X射线实验的定时监控器

时间分辨光学泵浦/ X射线探针实验通常用于研究结构动力学。为了确保高时间分辨率，有必要监视X射线脉冲和激光脉冲之间的时序。在非热熔融过程中从晶体固体材料到无序状态的转变可以用作可靠的时序监控器。我们已经以单次模式对InSb的非热熔融进行了研究，其中我们改变了样品温度以确定重复熔融所需的条件。我们展示了实验条件如何影响这种计时工具的可行性。
