    Summary:
    16:00 Started shift with Compton tuning in progress (Alexandre is in MCC). I=110 uA. Detector checkout and calibration ongoing in parallel (Vince).
    18:00 Compton tuning finished. Starting target cell centering study with raster on (~3x2.75 mm) and I=5 uA.
    19:15 Several magnets trip (L-Q1, L-D, R-Q1, R-Q3) due to a cryo hiccup. Starting recovery.
    19:30 Asking for controlled access, which was foreseen anyway, while the magnets are recovering. Planned work includes cabling and DAQ troubleshooting. At least one scaler was seen double-pulsing.
    22:50 Access finished. Asking for beam to complete the cell centering study. Taking many short test runs (see run sheets and separate log entries).
    24:00 End shift with cell positioning and centering studies in progress.
