Chad and I did the pressure test on TM2tube heater+(D) water  line at SHC with shop air.We tested from 30psi to 80psi on both side of D line. The bubbles were found at 50-55psi on blank off seal in SHC.

 I would like to correct this E-LOG. There is no real  leaking bubble had been found during the whole test according to the information supplied by Chad  Fisher during  this afternoon meeting. I would like to attach some pictures took from TH during this test.

Chad and I did the leak check on TM2 tube heater (+) water line  with blank off( + elastic o ring seal) installed on "D"  water block in SHC. We got the same no leak result as we got with rubber insert this morning.

Containment box has been removed and water block jig installed.

The blank off with the o-ring has been removed, manipulator fixed, circuit D water block sealinhg surfaces cleaned and blank off with c-seals installed and torqued. Leak check will occur shortly.

Circuit D has passed the vacuum leak check. Jig has been removed and containment box re-installed for move to conditioning station.

TM#2 moved from the south hot cell to the conditioning station.

Chad and I did the leak check   on TM2 tube heater (+) water line  with blank off and C-seal  installed on  WB at South Hot Cell.The line was easy to pump down to 0.0xE-9atm.cc/sec and 0.0XE-4 torr on leak detector. Chad flushed lot helium around the water block (10 sec spray). No response had been found on leak detector.

Ta#42 has been installed onto TM4. The "new" 9 pin connector was not an issue...attually went on better than any other previous one. Leaving the mounting screws loose on the target half allowed use of the manipulator to center the pins and insert them with ease.

TM#4 was checked electrically with and without target on it, see attached PDFs for details.

Chad and I leak checked TM4 HS line with Ta#42 target on the module. The leak detector base LR 0.0xE-9 atm.cc/sec, base pressure0.0xE-4 torr. Chad applied helium to the joints, and flushed the helium around the target. No leak has been found.I will do helium pressure test on this circuit at CS later.

TM#3 with no target has been moved from the south west silo to the south hot cell.

TM#3 electrical check at the south hot  cell with no target to give us a base line and show that things are ok with the module for the start of the running year.

Electrical test of TM#3 with TiC#4 attached. See PDF.

TiC#4 has been installed onto TM3

TM#3 with TiC#4 has been moved from the south hot cell to the conditioning station.

This Monday morning, Chad and I leak checked heat shielding circuit on TM3 with new target installed. The base LR on LD :0.0xE-9 atm.cc/sec, base pressure 0.0xE-4 torr. Chad sprayed helium twice on the VCR joints. No leak has been found. The circuit will be pressured with helium at CS.

TM#4 electrical check with Ta#42 attached post beam at the south hot cell.

TM#4 with no target has been moved from the south hot cell to the south west silo.

TM#1 with no target has been moved from the north west silo to the south hot cell.
