本数据集来源于 HEPS 储存环 2026 年 1 月至 6 月三个稳定供光运行时段的控制系统存档数据，共 89 天（2,136 小时）。三个时段分别为 P1（2026-01-18 至 2026-02-11）、P2（2026-04-04 至 2026-04-30）和 P3（2026-05-19 至 2026-06-27）；P1 与 P2 构成训练集，P3 为测试集。 数据文件包含以下变量： RF Frequency：主振频率，为低电平射频（LLRF）控制系统施加于主振荡器的频率目标值，储存环工作于 166.6 MHz 附近，单位 Hz；储存环通过调整该频率来补偿同步轨道周长的漂移； Circumference：等效同步轨道周长，由主振频率推导得到，单位 m； water_return_flow_1_6 / water_return_flow_7_12：储存环第 1–6 段与第 7–12 段的冷却水回水流量，用于表征冷却水系统的水力状态，单位 m³/h； solid_tide：固体潮等效周长变化，由 PyGTide 计算的理论面应变按圆环均匀水平形变换算得到，单位 μm。 每个变量均提供两级数据。raw 组保存控制系统归档的原始记录，包含整秒时间戳、数值、报警状态、严重程度与纳秒字段；processed 组将各通道对齐到完整的整秒时间戳（1 Hz），采用因果前向保持（仅使用该时刻及之前已存储的记录，不使用后续观测），仅保留时间戳与数值。 所有变量按时间对齐，可用于分析储存环周长的慢漂移与其环境、水力驱动因素之间的关联性。数据集可用于加速器物理及其与地球物理交叉领域的研究，例如储存环周长慢漂移的特征提取与建模、固体潮与冷却水流量对周长变化相对贡献的分解，以及慢漂移预测方法研究等。

The FXT instrument onboard the Einstein Probe consists of two co-aligned Wolter‑I modules (FXTA and FXTB) covering the 0.3–10 keV energy range, with a ∼60′ diameter FOV, a ∼30″ HPD, and a combined on‑axis effective area of ∼600 cm² at 1.5 keV. Standard scientific products include: orbit and attitude files, HK and MKF files, and both unfiltered and cleaned event files.

The High Energy Photon Source (HEPS) is Asia's first fourth-generation synchrotron radiation light source, whose beam orbit is highly sensitive to external disturbances. This dataset comprises ground motion and beam closed orbit data collected during user-operation time from January to June 2026, including 50 seismic events (based on the global earthquake catalog of magnitude 5 and above, with data from 30 minutes before to 2 hours after each event). The data include beam-related parameters such as beam current, feedback system status, and closed orbit data, as well as ground motion data from five measurement points near the storage ring. This dataset can be used to investigate the influence mechanism of ground motion on beam orbit.
