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.

Travis and I removed the 55 pin connector from the service cap today. The feed through was left in place as a new design for the replacement has yet to be designed. It was not possible to test if the cables could be pulled easily as I believe there is still 1 cable tie in the containment box. The wires were cut flush with the top of the copper tube in case Chad cannot remove them via the hot cell. Other items removed include several cable ties and a clamp used to hold a cable tie. The side panels on the service cap we difficult to remove so copper never sieze was added when they were re-installed.  I have attached some pictures from before and after a complete record can be found in the TM3 docushare folder.

Water interlock check  on ITW is done. All water signals are strong on EL panel.  ITW is configured to take proton beam.

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.

HS had been purged. The ITE is under venting. The TM4 will be moved to SH on next Tuesday which is May 21th.

I have been getting a fault on the roof top chiller for the 2 tandem 7.5 ton chillers. I have checked and we have water flow and the temperatures are nowhere near freezing. I believe they are over heating as the fans on that side are not coming on. The blades are free to turn by hand but the VFD controller keeps saying off. I have tried turning it on and off and that also did nothing. I have contacted ESC for further advice.

 Scott Adair from Riada sales came to site to complete diagnostics on the ONICON flow meter. He could not determine the problem and believes that there was a short in the head. He has taken the flow meter for what should be warranty repair. The flow meter is for diagnostics only, the conditioning station can still operate without it.

 A special thanks to Kazuya, Jane and Ray who jumped on this issue right away! The limit of the BIAS PS was set as 20000uA when in reality it is 4000uA. The issue has now been corrected. Please remember to divide the current by 5 for any elogs older than this one.

 To confirm that the sparking was coming from the module rather than the conditioning station TM3 was grounded and the conditioning station biased. Attached are the results. Highlights include that there was no sparking and the station was able to achieve 60kV (limited by controls from going higher). The current from the raw file has been corrected by the required factor of 5.

Manipulator has been sucessfully repaired. Recieved 0.19 mSv. Took Approx. 10-20 minutes

TM#3 with no target or source trays has been moved from the conditioning station to the NE silo.
