| Issue | Symptom | Quick Fix | |-------|---------|-----------| | | Over‑exposed spots, flat‑top intensity. | Reduce exposure time, insert additional attenuators, increase sample‑detector distance. | | Beam Drift | Sample moves out of the beam during long scans. | Re‑run find_beam_center.py every 30 min; enable beam position feedback (if available). | | Temperature Instability | ±2 K fluctuations in cryostat. | Verify cryogen flow, check temperature controller PID parameters, ensure good thermal contact. | | Pressure Leak | Pressure reading drops during high‑pressure experiment. | Tighten O‑rings, replace worn seals, check for blocked vent lines. | | Software Crash | GUI freezes, no new frames saved. | Restart the EPICS IOCs ( ioc_restart script), clear the HDF5 buffer ( h5clear ), contact beamline staff if persistent. |
