Coil line has been in RPG's ultrasonic decon over night. Initial swipes this morning picked up 5000 counts. It has been decontaminated to the point no more contamination is being found and nothing can be found with the frisker...so...it's ready for Maico and Dan?

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

Entry  Wednesday, July 15, 2015, 11:18, David Wang, South Hot-Cell, Repair, TM2, , leak check coil line(R,U) on TM2 at SHC 007.JPG008.JPG

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.

IMG gauge, clip for ground to window lines and gas line extensions were installed today.

David and I also tried to locate the short between the coil line and MSP/Heat Shield...it went away for a bit...but is back.

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.

Entry  Wednesday, July 22, 2015, 11:31, Travis Cave, South Hot-Cell, Standard Operation, TM2, no target, Electrical Check TM#2elecchksourcetraynotgt62515.PDF

Electrical check done on TM#2 around the 25th of June 2015, this was before the coil line leak was found.

Entry  Wednesday, July 22, 2015, 12:13, chad fisher, South Hot-Cell, Repair, TM2, , TM2 Short Findings TM2_Short_July_22.jpg

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.
