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

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.

Final polish, clean with methanol and clean compressed air.

Loop installed and torqued to 90 in lbs.

Minimum of approximately 1"  between loop and containment box at closest point.

Some issues with the turntable and having to wait for a decision on whether to remove TM2 from the hot cell so that TM4 with dead UCx target could be put in this morning.

Progress on TM2:

• Containment box has been removed from TM2.
• Water block jig has been installed.
• Existing blank off has been removed.
• Sealing surfaces have been inspected.
• First stage of sealing surface cleaning has been performed.

Tomorrow:

• Polish of sealing surfaces.
• Installation of loop.
• Vacuum/helium leak check of loop.

TM2_20141201_03 - sealing surfaces before cleaning...kind of dirty

TM2_20141201_05AC - sealing surfaces after cleaning...looks good!

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.

TM2 optics tray is complete.

Master alignment tray: 0 up/down, 0 left/right

Optics tray: Front 0 up/down, 0 left/right. Middle 0 up/down, 0 left/right. Back 0 up/down, 0 left right.
