 Wed Jan 10 10:22:41 2024, CB, JM, Some FEEs mounted - issues with Det#2 (bottom left) 
|
Started mounting some FEEs. We ran into some mechanical issues due to the new ERNI connectors on the new flexi-rigid adaptor PCBs. Davide skimmed 6.5
mm off the edge with the groove (the groove is gone). This is suffiicent to support the flexi-rigid and in spite of our earlier concerns, the flexi-rigid
can be mated/un-mated with the FEEs without major alignment issues. |

Thu Jun 22 18:58:02 2023, JM, TD, Slide back onto ring
|
The wire seal has been tightend further to 160 Nm. Open neg feed-through flange has also been fully tightend.
The CARME chamber was then slid back onto the aluminium frame on the ring. Two carriages were damaged during the sliding process, which have
now been replaced. Carriages were replaced by lifting one end of the upper frame section using the crane by only ~1mm. This was sufficient to slide out |

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.

Arrived at the control room to find we had lost connection to the power relay. We rebooted the nnrpi1 and re-connected according to the steps laid out
in elog 471 -> all okay
11:00 Restarted daq with no changes to the system from yesterday. Bias consistent with previous days. All pulser peaks are slightly improved |

The CARME chamber and interaction chamber were connected and section 9 has been fully closed. New valves have been installed on the interaction
chamber, in addition to new diamond windows. A leak cart has been connected to the backing line of CARME. Before begining the pumpdown, the manual valve |

Found all Merger Links background black - inactive. Nontheless the tapeservice was working, the data rate to disk was normal, and the file was being
written and the histograms were being updated.
Decided to stop DAQ, stop Merger, restart merger. Links rest to green background - but no more writing to disk! |
