 Sat Jan 13 14:25:05 2024, CB, JM, Bias tests with all FEEs connected 
|
Connected all FEEs.
The two top fees corresponding to the bottom right detector are connected to damaged flexi rigid PCBs. The top one is missing an pin that should
not be connected to anything, while the bottom one has a slightly cracked connector and is missing the top left pin. Spares should be in Edinburgh. |

Sat Jan 13 14:32:21 2024, CB, JM, Leaky manifold and cable management
|
Found two leaks in the welding of the manifolds, marked them in tape. Manifold to be repaired on Monday. Remember to re-install missing hoses, which
are in a bucket in the cave.
See attached how it is supposed to look like. |

11:00
Changed slow comp threshold to 0x32 (500 keV). Checkloaded.

Fri May 31 19:12:01 2024, CB, EM, Run 13 - test with beam
|
20:00
The beam is set at the correct energy, operators cross-checked it again. What we see at 750 is due to the molecular beam. The operotors
are trying to optimize and get rid of this in the next 30min. |

Fri May 31 21:03:21 2024, CB, EM, Run14
|
22:03
Before this run we checked quickly beam with the target on but it does not make sense with the current status of the beam.
We removed target and starte Run14 |

Fri Jun 6 16:49:59 2025, CB, AY, ST, Beam overlap results for 200keV and 250keV
|
For 200keV the optimal horizontal position is -5mm.
For 250keV the optimal horizontal position is -2mm.
Both values are already given to the operators, so tomorrow we can just switch to 200keV and go on :) |

Mon Jun 16 22:06:00 2025, CB, AR, EW, RUN 90-91 14x

23:00 DAQ restored and data now being written okay. Checks all okay, see screenshots below. Histograms reset. 40 bars in bottle @ 23:45 - should last
30 hours.
12:00 Checks all ok. No problems with aidas or writing to disk. |

Thu Sep 2 21:04:26 2021, CB RSS ML + DR OG, Gate valves mounted + pump down 6x
|
Mounted both gate valves and support. Gate
valves could not be installed one bolt
rotated from 90 degrees as per drawings

Fri Sep 10 10:50:55 2021, CB RSS ML, Pressure after overnight pump down
|
Pressure found in 10-7 mbar range.
Decided to leak test anyway for safety.

Wed Sep 8 17:03:07 2021, CB RSS + OG NB, Six feedthrough flanges mounted 23x
|
Continued to mount flanges as per previous ELOG entry.
Peter also remarked that the wires look a bit loose inside the holes, although this is how they were during
dirty tests in Edinburgh.
