I did a 5KV mega test on TM3.  Only5Mohm @5kV between coli line PQ and chassis(ground). It confirmed the close gap between P,Q and GE. Other lines are ok. See attachment.

See attachment for sparking signs of the water lines mentioned  above (Coil and Ground Electrode lines) in TM3 Source Tray.

PLEASE NOTE: the resistance values for A and B on David's attachment are not correct since these measurements were done after Chad removed the target and the heat-shield bracket was moved, so consequently the water lines were not at their nominal locations. Once they were back in plac,e David took another measurement and the resistance values for A and B showed also 3,000 MOhm (as it was for most of the lines). The only lines that still showed a low resistance were the Coil lines. 

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.

The ITW is configured to take proton beam.

I moved 5 shielding blocks to ITW this morning .I checked the water signals in electrical room before the moving, and everything is fine. The argon venting systemin ITW and electrical room is ready also.

5 SHIELDING BLOCKS HAD BEEN MOVED OUT OF ITE.AIR SAMPLE AND SWIPED FIRST BLOCK AND ITE PIT.NOTHING HAD BEEN FOUND ON ALPHA MONITOR AND OTHER TWO MONITORS.

5 shielding blocks had been  transferred from ITE to ITW.  The  ITW is configured to take proton beam.
