after run 45 I reset all spectrums and number_Ge_15 dedector not taking data.
i check the fans_monitor_scaler (EAGLE_array_monitor) monitor and number 15 Ge, number ACS 5 never change the color just staying white there is a problem.

There was a problem with the beam from 20:19 to 20:30.
Now it is fine. |

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.

longer break during chane of plunger distance due to technical problem, you can not move plunger to larger distances, so now we are choosing smaller distance in the morning we ask the specialists

As in the title, see below.

Greware is also seeing data.

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. |

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). |
