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. |

Wed Mar 8 11:42:14 2023, IK, Problems, , General, Run 49
|
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.

Data from current run - 35, with limited beam current and rates - see a recent post by Güray.
BU level, so what we see in Greware (both online & nearline).
Attached is the fold of Germaniums.

Thu Mar 9 01:41:50 2023, GJ, Problem Fixed, , Hardware, TS zeroing - cables to S-IN from VME controller - between runs 49 and 50
|
Since we were observing jumps of 16 ns in timings of all channels of whole boards, the assumption was that the
signals from logical FIFO arrive at different times to S-IN inputs to zero the TS counters.
6 originally placed cables of quite the same length were replaced with 6 cables of declared 3-ns length, same
