TM2 coil line R,U has been vacuum leaked check at the hot cell and has passed with no response from the leak detector.

  998   Wednesday, July 15, 2015, 11:18 David WangSouth Hot-CellRepairTM2 leak check coil line(R,U) on TM2 at SHC

Chad and I leak checked the coil 1 circuit(R,U) after rebuilt coil line is installed on TM2 source tray. The pumping down on the circuit is very quick and smooth. The LD base lake rate 0.0xE-9 atm.cc/sec. Base pressure0.0xE-4 torr.

Chad sprayed lots helium on the R( coil 1+)and U(coil 1 -) water blocks. During  1 minute waiting time, there is no any response on LD. The R and U water blocks and C-seals are leak tight.

Gas lines extensions installed yesterday were too long and gas lines touched top inside of containment box. They have been removed and the gas lines re-installed in their original manner. Gas lines have been "adjusted" as to clear the tube heater lines, which was the original issue.

  1009   Wednesday, July 22, 2015, 12:13 chad fisherSouth Hot-CellRepairTM2 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.
