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.

White beam Laue diffraction dataset of CaSTS protein crystal; dataset was collected via single-crystal helical translation data collection strategy.

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.
