Alpha background gathered from 17:35 12/2/22 to 13:44 13/2/22 is run32. Run time ~20 hours. Some alphas visible in aida1 1*L histograms attached.
Noticed grounding of crimps that attched to cryring ground has come loose. Those crimps not ideal for our grounding cable so were loose. Grounding
cable from each fee now meet at a single grounding cable joined by an m3 nut and bolt. This grounding cable then goes to the cryring ground and |

Beam OFF. Run started 20/2/22 18:42
Fast comparator threshold HEC set to 0xff for all fees and asics to combat high energy noise bursts.
Electron cooler scalar plugged back into aida03 ~3000 per sec. |

Alpha background started with beam ON - run47. Run started 16:49 18/2/22 (beam subsequently found to be OFF)
Beam energy 4 keV, beam lifetime ~ 100 ms
Noticed aida01 and aida02 were showing increased good event rates to ~250,000, effect seen on spectrum browser and data writing rate increased |

Moved cables that touched neg pumps. See
photos. Please bear in mind perspective.
Note avoiding touching chamber

|
Mon May 1 18:21:18 2023, CB, JM, All detectors mounted
|
Mounted four detectors on Carme ad well as four cable harnesses.
Cables for new, shorter harnesses appear still too long. Likely the model is not correct somehow. |
|
Tue May 2 15:02:09 2023, CB, JM, All detectors and harnesses mounted
|
Completed mounting harnesses and detectors.
The strain relief support for the bottom most two detectors on the feedthrough side was not mounted because we could not find enough MACOR parts
and mounting flanges. We cannot find them in GSI, possibly they are somewhere not obvious in Edinburgh. |

Thu Jan 11 19:57:20 2024, CB, JM, All FEE holders mounted
|
After discussions with Davide, changed the holes in the FEE holders for the bottom-right detector to slots in order to slightly change the angle that
the FEE inserts into the flexi rigid PCB. This was sufficient, with some difficulties, to insert both FEEs into the flexi rigid.
Attempted to finally mount the last two fees, the top two for the bottom-right detector, which should have been very easy. Somehow managed to |

Thu Jan 13 10:33:24 2022, JM, OH, TD, Adaptor Board misallignment
|
The ERNI connector is not central on the adaptor boards causing misallignment with the FEE.
The adaptor board is 80mm long. The ERNI connector is 50mm long. The connector is 13mm from the 2x Lemo side and 17mm from the 3x Lemo side.
This results in misallignment between the FEE and adaptor board. |

Ion pumps de-gassed by switching on and off multiple times. Large pressure increase the first time pumps were flashed, pressure recovers quickly
once pumps off. Subsequent flashing of ion pumps showed a significantly smaller pressure increase, unitl little increase was seen. |
