Current readout issues from beamdump. Beam stopped from 17:46-17:52, run 36 ongoing.
MP & GJ checking the grounding and connection the beamdump readout. No visible issue found in the exp hall, but copper grounding wire
was tightened, which seemingly resolved the issue (stability of beamdump readout). |
