Entry  Tuesday, November 10, 2015, 10:23, Anders Mjos, Conditioning Station, Maintenance, TM3, , Air to vacuum leak on service cap TM3_Service_Cap_Leak.pdf

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.

Target conditioned by ISAC operators to 30 kV without any problems.

EE current limit increased to about 26 mA in an attempt to recover. Cooling down target to investigate.

 After conditioning over the weekend the EE developed a short. This was confirmed by measuring the resistance between EE and Heat Shield on the module yesterday.

 It was found that the conversion from voltage to vacuum (Torr) in EPICS is not correct for the XGS-600 controllers in use at the TCS. EPICS did not correspond to local values displayed on the controller. An e-fault has been submitted.

The high active water resistivity took a long time to recover after the upgrade to the water cooling circuit. The system needed about a month (from end February to end March) to recover to nominal values. See attached plot of archiver data.

TM1 has now been connected in ITW and the water resistivity remains > 8 MOhm cm, which should allow normal operation. However, the resin is suspected to be approaching end of life. Work is ongoing to get a new replacement resin tank.

A leak was found on the o-ring between the module flange and TCS. This could be fixed by cleaning the o-ring and sealing surface. The Window line is not closed and was accidentally pressurized with He on April 25
