Beam drift in the horizontal direction (XTD9_XGM x position) started at around 10am and continuously drifted until 16:00.
After then, beam has been drifted back to original position within 4 hours. |

Beam drift in the horizontal direction (XTD9_XGM).
From ~16:00, X-ray beam started to drift in the horizontal direction. In total, ~0.3 mm drift observed within 2-3 hours.
