Issue described in #61 continues to persist.
Beam stopped from 19:20 to 19:32, run 36 ongoing; MP, GJ, BS entering the experimental hall.
They changed the position of the grounding point on the chamber, moving it downstream after a fitting/joining part (A to B on the attached picture [artist: GJ]).

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). |
