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). |

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 |

Wed Mar 8 07:57:05 2023, IK, Problems, , Beam, beam unstable
|
The beam was unstable from 7:55. Stabilized around 8:03.
Counting rates are higher, EAGLE det4 went to ~2.5kHZ from ~2kHz (attached).
According to the operator, a bit of a tuning was done, current is 1nA. |

Counting rates continued to increase (det4 > 3kHz). Beam current looked fine on the beam dump, but beam is fluctuating, and can reach 2nA on the collimator.
Asked for improved focusing.
Attached screenshots and Ge spectra from before changing anything. |

As in the title, see below.
The data are still being constantly written on the disks with usual rate (also visible on grafena).
Greware is also seeing data.
