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

no beam in 15:52 - 16:21 due to power supply problem

Run 36 Started

New Beam energy is 150 MeV

The beam dumb currennt is 2.5 enA.

Plunger run = 282

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 picture [artist: GJ]).

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.

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.

Run number: 0
Trigger: g
Start time: Mon Feb 27 02:43:50 2023
Stop time: Mon Feb 27 03:21:01 2023

Two Eu sources hanging in more or less focus points of two partially open halves of EAGLE.

Notes of the measurements with different conditions are attached.

Conclusion:
What is read out by the operators on the blue cable should be multiplied by 7 to get a real value in enA.
