As previously mentioned, dump target installed with new mounting and high current fasteners.

Leak Check complete and ready to move to CS at 1:30

The source tray has been removed from TM2.

TM4 optics tray was installed onto the old TM2 source tray yesterday and tray filled with non-active metal scrap. Tray inserted into transfer frame 95% yesterday. During insertion the ball nut of the transfer jig became unfastened from its drive plate. This will have to be fixed before the jig can be used reliably again however we were able to finish the job...the transfer jig is 20 years old now so it is not entirely suprising that it needs some attention.

Today the Tm2 tray final install into the transport tray occurred by driving the tray drive screw and bringing the tray into the transfer frame the last inch 1/2 or so. "Feet" (ITA2380) had to be removed from sliding tray assembly to fit in the box however upon attempting this is was immediately clear that one of the screws was stuck and must have been cross threaded during assembly. As as result the entire drive bracket (ITA2375) had to be removed form the source tray to allow final insertion into the box.

11 handles from spent target transfers, 1 plastic bin box, Ta LP test target TRI coil, 1 aluminum box, sockets and extensions from spent target transfers and 5 obsolete legs from previous source tray replacements were amoung the items disposed of with the spent source tray.

The containment box has been removed from TM2, the Enzel lens and steerers disconnected and optics tray removal has commenced.

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.

Today cleaning and polishing pads were inserted into the hot cell.

Module side waterblock jig installation was attempted however one of the locking tabs/latches (ITA2405?) came undone/fell off. Luckily, I had old, obsolete jigs in the hot cell so I was able to remove parts I needed from an old one and rebuild the current one.

Jig was installed on module to retain module side waterblocks.

Blank-off remove was commenced, however due to and large amount of water coming out of the line to have the blank-off removed work had to stop till the water evaporates.

Waterblock sealing surface cleaning and polishing will continue tomorrow.

Also, upon installing the jig a piece of fiberglass that had previously been manual inserted between two of the water lines (early to mid 2000's) fell out.

 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

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

Final inspection took place with Pierre, Grant, Friedhelm and Anders present.

Two action items were raised:

1) check routing of 9 pin connector line

2) Check orientation of 9 pin water block

Chad pointed out concerns on clearances between a target and conductor block waterlines, possible optics tray alignment issues (that it had changed slightly from the initial alignment), and gap between steerer housing and ground electrode due to alignment.

Final Alignment checks of the TM2 source tray took place today.

Mater Jig: Front - 0,0 Back - 0 left, right, .005 low

Tray: Front .001 High, .001 right Back - .001 right, .008 low

Which equals  Tray: front .001 high, .001 right back: .001 right, .003 low in comparison to the master jig which is both within spec and within reason to pre-soldering numbers.

Steerer was out significantly and currently sits at .003 high, .002 right wrt. master jig.

More refinement on the steerer tomorrow and check on the optics tray as well.

Final alignment continued this morning.

Steerers have been aligned to 0.001 low, 0.000 left/right wrt master jig.

Optics tray required some adjustment as well and is now at:

Front 0.000 left/right, .001 high wrt master jig

Back 0.001 high, 0.000 left/right wrt master jig

Febiad coil conductor blocks have been reset with the master target jig as well...as they have been on and off during the test stand test.

A few components have been removed during the test stand test (such as feet required for tranfser jig) which I will now hunt down.

Otherwise i believe we are ready.

Source tray for TM2 has been moved to the alignment area by Dan and co.

This morning Dan removed the c-seals used during the test and he and I inspected the sealing surfaces to determine if they need to be cleaned...they do..trace indium was present on all blocks.

Surfaces will be cleaned before final alignment check.

TM2 SiC#6 has been disconnected in ITW. See check list

TM2 has been connected  in ITE.  All turbo-pumps are started.

TM2 was connected in ITE 12th Nov. attach checklist

The results  are good. See attachment.

 Electrical check result is fine.  See attachment.

TM2 was disconnected in ITE yesterday.

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.

 electrical checked in ITW
