|
Ge rates increasing, similar to what it was 24h before. Asking to decrease beam intensity by a factor of 2.
Attached Ge spectra before decreasing.
Before decreas beam current was 1.75enA, afterwards 1.1enA. |

Count rates are still a bit high (~2.6kHz for EAGLE det4). Ge spectra looks fine compared to earlier ones.

|
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). |

Fri Mar 3 19:41:27 2023, IK, Problems, , Hardware, Beamdump readout issue Vol.2.
|
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]).
