    We did the following check in the hall:

    1) Transverse laser alignment: we adjusted the laser spot slightly (~0.5cm)
    2) Transverse rotatable Q-wave plates angle: moter#1474 is very good,
    motor#0338 got re-calibrated and the change is 1.7 degrees.
    3) Laser power measurement: 57.6 W in total (no big change)

    Even the additional gradient from the small correction coil didn't help,
    we decided to leave it on (0.5A) to reduce the masing effect for future
    EPR measurement.
