The TM2 optics tray has been transferred from the source tray to the transfer fixture in preparation for installation of the source tray into the module.

 The following work was done on June 18 2015:

- Finished cleaning and polishing all water blocks on module side (white felt with isopropyl, then buffing material with isopropyl, then canned air).  Heat shield waterblock re-done because water marks visible (white scotchbrite, white felt w/ isopropyl, buffing material w/ isopropyl, then canned air).  All surfaces looked very good, no lint or scratches visible.  
- Tray installed using installation jig (jig was very difficult to slide on hot cell table).  Window circuit waterline bracket tube retaining screws had to be removed for the sourcetray to clear the module frame.  Optics tray locating mushroom on source tray rubbed against the module side waterblock jig and was pushed past.  Gas lines were held clear of the source tray with the manipulator as the it went in.  The nut on the source tray side water block guide pin had to be loosened to facilitate complete insertion of the source tray.
- Connection of waterblocks for circuits D, C, B, A, Febiad Coil 2 were done in the sequence listed with no issues
- Extraction electrode and heat shield water blocks could not be done up initially because the locking tabs could not be undone (interference with module side jig bracket)
- Ground electrode waterblock connected without issue
- Window waterblock attempted: screws would not engage
- Febiad coil 1 negative waterblock source tray side locking tab had to be re-inserted into block, then waterblock was connected
- Febiad coil 1 positive connected without issue (failed initially due to shorter screw)
- Mounting support plate waterblock alignment pins did not engage initially, rotated source tray side waterblock using polishing tool.  Then was connected without issue.
- Extraction electrode waterblock revisited: pulled together with 1-5/8" screw, then connected (with 1-3/8" screws in both holes as per ITA6144)
- Heat shield waterblock revisited: installed without issue (as the jig had been pulled together by the previous step)
- Attempted window water block again.  Right side manipulator wrist tong cable broke while using camera.  Waterblock could not be connected (holes look concentric, pins engaged, blocks together and almost flush)
- All waterblocks except window waterblock torqued (tool did not slip properly, so torque will be re-checked)

Plan for Friday June 19:
- Put blank-offs and various fasteners in hot cell through tool port
- Check torque of all waterblocks with dial torque wrench
- Attempt window water line again with different fasteners (non-blunt start), try removing both sides of waterblock alignment jigs
- Install blank-offs on window and heat shield lines (VCRs)
- Perform preliminary leak check

Window waterline has been successfully connected using 1 1/2 inch long non-blunt start 1/4-28 bolts.

All bolt torques have been checked with dial torque wrench and are confirmed to be tight to 90 in lbs.

Left manipulator now broken. Master side however, so repair can take place Monday or Tuesday.

The master wrist/tong cable has been replaced on the left manipulator. Everything appears to function well so far.

Both halves of the water block jigs have been removed and the module is now ready for base vacuum leak and electrical checks.

During removal of the jigs the fiberglass that had been "shoved" by hand in between two of the lines in the early 2000's fell out again.

The following circuits have been vacuum leak checked and have not registered any leaks:

Circuit D, C, B, A, Coil2, EE, Ground Electrode, Mounting Support plate, Coil 1.

Left are Heat Shield and Window circuits which will be checked after blank offs are installed on the vcr terminations.

All water blocks seals and joints have been leak checked. No leak has been found on any of them. See attachment

On June 25th the following work was completed:

Optics tray was installed into TM2. The lower fastener on the vertical cable tray (IRH1585) needed to be removed and vertical cable tray rotated upwards as optics tray would not clear cable tray. Optics tray was intstaled, cable tray repositioned and screw re-inserted.

Modified water block for 9 pin connector was installed.

Steerers connected.

Ground Electrode water blocks were "repositioned" closer to there specified position to attempt eliminating the short between the ground electrode line and coil 1 circuit. This was successful but could still use a clamp or other method of ensuring the ground electrode line is in its "proper" place.

9 pin connector line was rerouted to ensure it does not contact anything it is not suppose to (Rerouting directions provided by Anders).

Enzel lens cable was installed.

Blank offs removed from window water lines and new gaskets installed in preparation for installation of the containment box.

Containment box window waterlines have been connected and leak checked and new containment box cover installed.

Module ready for transport just before 9am.

The right hand manipulator has been repaired. It took 43 minutes and I received ~ 0.56 mSv

UCx#12 has been removed from TM1 and placed in a pail with argon.

Right leg (B) of target is clearly broken.

Containment Box cover re-installed and module ready to move.

TM#1 has been moved from the south hot cell to the south west silo.

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

First thing this morning the hot cell was "cleaned up" in preparation for the return of TM2 for attempted verification and locating of leak on R/U coil circuit.

Containment box has been removed and front cover reinstalled to provide some modicum of shielding form the entrance and exit windows. Box was placed at an angle in the corner to try and minimize line-of-sight with potential worker(s).

Did notice some funny discoloration of both sides of coil water block "R" as seen in attached picture.

Field measured at block "R" through tool port with pole monitor is 6.65 mSv/H.

There are three air hoods and two air lines currently available.

R U coil line removal started at 11:30. Water block jig installed and coil line disconnected from module.

Chad and I leak checked coil line(R,U) on TM2 at SHC yesterday. The leak detector was pumped down to 0.0Xe-9 atm.cc/sec before the check. Chad sprayed helium on the soldering joints connecting the cooling copper lines to the small holding blocks for the coil terminal(R,U).  After sprayed helium 2 seconds, I saw the leak rate on LD started to climbed up. The highest leak rate is 4.0xE-8 atm.cc/sec. It is a very positive response. We waited the leak detector pumped back to 0.0xE-9am.cc/sec, and tested again on the same joints. The result is same. Chad also sprayed helium on the R,U water blocks to check the C-seal. I saw a delayed tiny response on LD ( from 0.0 to 1.3xE-9atm.cc/sec). We think this tiny response is caused by the helium drifting to the leak soldering joint, but not a real C seal leak.

July-06, 2015. Chad , Grant and I did the bubble test on R,U water blocks. We suspected the leak on the R,U circuit is from C seals on the water blocks so we did this test first. I applied both air and helium to R,U circuit , Chad applied snoop soap on the R,U water blocks.The air and helium pressure was increased from 40 psi to 90 psi Max step by step.Chad did not see any bubbles on the water blocks during the test. Since we did not find the leak source, we decided to do vacuum helium check on the all joints and c-seals of the R,U lines later.  Finally, We found the leak by vacuum helium spray the day after this bubble test. See other e-log.

Water block jig has been removed. Stuck source tray side water block jig component has been removed. An attempt was made to connect the gas lines to there bracket however they contact/interfer with the tube heater lines...Anders is looking into a solution.

Containment box and front cover have been replaced and TM2 is ready to move to the silo.
