    Shift Summary

    16:00 Shift started and Hall is still in Resitricted Access.
    16:10 Half-wave plate was taken out.
    17:40 Hall is now closed and in beam permit.
    18:40 MCC could not turn on the chicane magnet, caused by a local switch. An access was taken to address it.
    19:00 Jack came in and helped remove the lock, hall is back to beam permit.
    19:30 Moved target to Empty positon for beam tuning.
    19:50 Turned off slow raster.
    20:20 Inserted half-wave plate.
    21:10 Turned on slow raster and moved to holely targets to center the beam.
    23:40 We found that there is a signifcant offset in the target ladder, about 1 cm, and MCC could not tune the beam to completely cancel this large offset. So we decided to continue the run plan by putting an offset in the target ladder control.
    23:50 Target ladder is stuck, called controlled access to fix it.
