Monday, November 09, 2015, 16:47, Anders Mjos, Conditioning Station, Maintenance, TM3, FEBIAD Test Target, Leak check of Service Cap
|
Service cap leak checked this afternoon. Found multiple leaks of 10E-8 to 10E-7 range. Connected to the backing line with IG1 at ~4E-6 T, CG1A around 40 mT. Got responses around large round flange on top, rectangular side panels, water f/t on GND and water f/t on HV. Will resume leak checking tomorrow to attempt to pinpoint sources of leak more accurately. |

Conducted a more thorough leak check this morning with Edi. He found a leak on the base of the blue F/T insulator for the multi-pin connector (see attachment). I discovered that all the bolts could rotate freely in the threads as they were too small. The bolts were replaced. The leak rate was reduced but still significant. The o-ring will likely need to be replaced.
Tuesday, November 10, 2015, 17:00: Could not find new o-ring. Cleaned groove and o-ring and applied o-ring grease. Re-attached F/T. |
