Wednesday, July 22, 2015, 12:13, chad fisher, South Hot-Cell, Repair, TM2, , TM2 Short Findings 
|
Pin X was unplugged, short remained, however any slight pressure on the block towards the source tray makes the short go away.
Confirmed clearance between the EE and thr R / U coil lines as well as MSP of coil line.
Camera inspection would seem to indicate that ALL issues stem from a common location...there is a spot where both the pin X waterline and the one of the R / U waterline contact the heat shield waterline...one on one side of the heat shield line and the other on the other side.

Wednesday, August 19, 2015, 14:52, David Wang, Conditioning Station, Repair, TM2, , TM2 at CS
|
During the TM2 HV test at CS, It failed. In order to confirm there is no any water leak inside the module after the heaters and beam extraction test, I disconnected all the water lines on the TM2, and purged the water lines with pressure air. Leak detector was reconnected back to the TM2 service cap, and all water lines are pressurized with 80psi helium again each for 2 minutes.No any leak had been found during the test. All the water lines are still perfectly sealed. Also, I checked all the vacuum to air seals on the top of the module.They are good either. Anders used the RGA tracking the helium during the test. No leak. |

During last run， ITW dump circuit had a water leak on an adaptor below the pressure gauge. The top tank flange, slot, and O-ring were water contaminated by the leak. I removed the old o- ring, cleaned up the flange and o-ring slot, and put a new o-ring into the flange. Some pictures will be attached in this mail later. |
