Six feedthrough flanges mounted |
|
|
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.
Attempted to pack the wires in two holes rather than 4 - too tight. Cannot close.
Packed the wires in 3 holes instead. Better, but still a bit loose. Wire harness feels quite robust and no
obvious strain is placed on the connectors.
#1 flange left with four strands for now.
Connectors were tested in this way in Edinburgh for motion tests. No broken cables after several thousand
repetitions.
Had troubles with second flange being mounted. Glove was caught under MACOR connector. Managed to free it
somehow with a cleaned screwdriver. Other half of the flange refused to go in due to bent pins, until NB was
able to repair it.
Mounted as #5.
Most other connector pins OK. Had to adjust a very small number. Cause of damage unclear - transportation? See
photos.
Took some pictures inside the chamber. Most connectors look OK, but
- One harness is touching the NEG wires (#2). This could be an issue. Will try to move it tomorrow
- Wires hanging from the top may be putting a lot of weight on the connectors. See pictures. Given number of
wires this may be acceptable.
- One harness is touching the NEG cage. Definitely an issue. Will fix tomorrow
Top/bottom flanges mounted with short harnesses. Side flanges mounted with long harnesses.
Two flanges left to mount.
Only #1 has been tightened. Other flanges left finger tight for Grossmontage to tighten properly tomorrow.
Outside motor to be fixed tomorrow. |
