Both Turbo Pumps are now operational.

With the Turbo pump replaced I have started roughing at 10:48

 Turbo Pump 2 has been replaced on TM3. I got a count of 350 on the sleeve of my tank suit.

 Turbo Pump 2 has been replaced on TM3. I got a count of 350 on the sleeve of my tank suit.

 Both Turbo pumps on TM3 have failed. They were both attempted to start in soft mode. TP2 could only achieve ~19kpm and TP1 ~10kpm. I have turned off the scroll pump and vented through the turbo pumps.

TM#3 with no target has been moved from the south hot cell to the conditioning station. Move went well. The fields around the module was 1.6mSv/hr.

5 shielding block had been moved  back to ITE. The ITE is configured to take proton beam.

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.

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.

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.

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

New gaskets and fasteners have been inserted into the south hot cell in preparation for installing the dummy target onto TM3 tomorrow.

I leak checked new installed ITW EXIT1 tank to module o-ring.No leak had been found . Also ,TM1 primary vessel air to vacuum seals had been checked at the same time. There was no response had been found on leak detector.

TM1 has been reconnected in ITW. Water interlock check for TM1 is done.

On April 08th, all water lines in TM1 had been helium pressure tested(70psi) at conditioning station. No leak had been found.

TM#1 with Ta#39 has not passed it electrical check again, while sitting at the conditioning station at air. The readings have not been consistant. See the current PDF for details.

TM#1 with Ta#39 electrical check at the target station see attached PDF (CHK 4).(April 9th 2013) PASSED

TM#1 with Ta#39 electrical check at the target station see attached PDF (CHK 5).(April 10th 2013) PASSED

 TM1 started venting at 4:15 pm with Argon. I will leave the valve open over night.

TM#1 with Ta#39 had the electrical check done on it again it passed, changes this time were the water lines were purged and it was under a better then roughing vacuum. See the attached pdf for details.

TM#1 with Ta#39 at the conditioning station, has failed its electrical test see attached pdf for details. Also while setting up for the electrical test one of the high powered flexible connectors popped out its crimp and another is working it out its crimp.

Roughing started at 12:06. It was believed there was a problem with the compressed air but there was none, TM1 doesn't leak and so you cannot hear that the connection is made.

 Roughing stopped as the module and cover requires modifications that require the vacuum to be opened.
