David Wang | South Hot-Cell | Repair | TM2 | | 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. |

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.
