TM#3 has been moved from the NE Silo to the south hot cell, move went well.

Front containment box cover has been removed and heat shield circuit blank offs removed in preparation for installation of dummy target.

Ready for baseline electrical tests and 9 pin cinnector tests.

The heat shield circuit blank offs have been re-installed and front cover replaced. TM3 is ready to move to the conditioning station for testing.

Electrical check was performed on TM#3 with no target nothing was wrong was found, but our megger does not go above 1000 volts so any problems above this value would not be seen, see attached pdf for details.

Also the 55 pin(top) double 9 pin (bottom) connector was tested as well. When it was meggered to 60kV common more then 50% of the lines failed, when those line were identified with a resistance package two were unable to be indentified. The wiring for this double 9 pin connector should be removed to prevent HV problems. New wiring is not physically possible to re-install in its place, see the PDF for the wiring details.

TM#3 has been moved from the conditioning station to the south hot cell, move went well.

Work on TM3 source tray removal started at 10:40 am today.

The containment box has been removed, and disconnection of the optics tray is 90 complete.

Pictures can be found in the April Refurb Work Folder in the tm3 rev3 refurb pictures folder.

Optics tray has been removed from module.

Waterblock jig installation has commenced. Of note, jig installation on TM3 has proven more dificult than the previous installation on TM2. Many of the waterblock assemblies are skewed (not perpendicular to plane that they should be...perpendicular to).

As I am away tomorrow, jig installation willl continue on Friday. With the source tray hopefully being removed on Monday.

The back half of the water block jig (services tray side) has been sucessfully located onto the module.

About 50% of the waterblocks have centered themselfs it their respective cups and the rest look good for concentricity but will require some gentle wiggling to get them to seat.

Service tray side of the waterblock jig is installed and all locking tabs enagaed save the heat shield circuit. Locking tab for heat shield circuit with be worked on Monday morning and installation of the source tray side of the waterblock jig should commence on monday as well.

Chad removed the source tray from TM3  today, see attached picture (video was also taken). There was some interference between the window cooling lines and the frame work as well as the clamps for the ground electrode and the water block alignment jig. There was also interference between the optics alignment post (specifically the mushroom top) and the water block alignment jig. Investigation into these inferences needs to be completed as they could cause trouble for the insertion of the new source tray and alignment of the copper lines. During removal it was easy to bend copper tubes out of the way but this clearly would not work during installation.

The source tray has sucessfully been removed from TM3.

I will put a report in the TM3 rev 3 docushare directory as there were some items of note during this procedure.

David and I checked circuits p and q (the water cooled coil ciruit) for flow this morning as, with the source tray still in the module, there was both a leak and a leak tight blockage. Both p and q allowed air flow through them confirming that the blockage was in the surce tray side of the system.

The heat shield circuit was also tested for flow and it passed.

David and I preformed a helium leak check on the service tray waterblocks and verify that no damage had been done during jig installation. All 14 circuits were checked and verified to be ok except circuit E and circuit I which were unstable when helium was applied. The resonse time on E and I would suggest that it is an issue with the bungs that were used and not the braze joint however.

With the aid of nic new manipulator snap fingers made by Maico the peek cable ties restraining the 9 pin connector wiring to the gas lines have been cut.

The 9 pin wiring has successfully been removed from TM3.

Checks of the wiring for the IMG are complete and have passed.

The source tray for the mock-up has been setup for waterline bending and soldering/brazing.

Thanks to Travis for finding the photos for the TM3 rebuild that took place in the anteroom in 09' and Maico and Dan for the support in ironing the issues with the source tray side soldering issues.

The source tray side of the water block jig has been removed in preparation for moving the module to the  conditioning station for electrical tests.

the containment box has been reinstalled onto TM3. After electrical checks it is ready to move to the conditioning station...for electrical tests.

TM#3 with no target and no source tray has been moved from the south hot cell to the conditioning station.
