X-ray free-electron laser (XFEL) pulses from SPring-8 Ångstrom Compact free-electron LAser (SACLA) with a temporal duration of <10 fs have provided a variety of benefits in scientific research. In a previous study, an arrival-timing monitor was developed to improve the temporal resolution in pump-probe experiments at beamline 3 by rearranging data in the order of the arrival-timing jitter between the XFEL and the synchronized optical laser pulses. This paper presents Timing Monitor Analyzer (TMA), a software package by which users can conveniently obtain arrival-timing data in the analysis environment at SACLA. The package is composed of offline tools that pull stored data from cache storage, and online tools that pull data from a data-handling server in semi-real time during beam time. Users can select the most suitable tool for their purpose, and share the results through a network connection between the offline and online analysis environments.
来自日本兵库县的Spring-8 Ångstrom紧凑型自由电子激光装置（SACLA）的X射线自由电子激光（XFEL）脉冲，其持续时间小于10飞秒，在科学研究中带来了诸多益处。在之前的一项研究中，开发了一种到达时间监测器，通过按照XFEL与同步光学激光脉冲之间到达时间抖动的顺序重新排列数据，来提高3号光束线泵浦-探测实验中的时间分辨率。本文介绍了定时监测器分析仪（TMA），这是一个软件包，用户可以通过它在SACLA的分析环境中方便地获取到达时间数据。该软件包由从缓存存储中提取存储数据的离线工具和在束流时间内从数据处理服务器半实时提取数据的在线工具组成。用户可以根据自己的目的选择最合适的工具，并通过离线和在线分析环境之间的网络连接共享结果。
