TM1 was high voltage tested without a target on November 16, 2011 with Don Jackson, Pierre Bricault, and Bevan Moss. The module was able to hold
up to 25 kV but between that and 32 kV there was lots of discharge which could be measured in the vacuum. See the attached plot for the voltage current
and sparks. |

High Voltage (HV) testing was completed on TM1 today. Vacuum was very good 1.9 x 10^-7 T in the service cap, 3.2 x 10^-7 in the containment box,
and 2.0 x 10^-6 in the secondary. The voltage was successfully brought up to 27kV with a current draw of 0.12mA and o sparking. At the next step, 30 kV,
the current draw was above 0.3mA and sparking was beyond 20 sparks per minute. The module should not be taken above 27kV. There is the possibility this |

ITW and TM1 winter shut down vacuum leak check had been finished yesterday.All ITW primary vacuum vessel, secondary vacuum vessel, and TM1water lines
had been leak checked.No any leak has been found .The ITW and TM1 are both leak tight.Some detail information below:
TM1 and ITW primary vacuum vessel and water lines: The leak detector was hooked on BV2 after TP2. Calibrate leak detector.leak |

UC#3 was removed from TM1 this morning. Upon removing the oven heater bolts BOTH legs fell demonstrating that both sides of the oven tube have
broken off from the central block.
Target was put into a can under argon for disposal after the module is removed from the cell. |

An autopsy was performed on UCx#3 yesterday afternoon. This autopsy followed the plan written by Anders. Indeed, both sides of the target oven had seperated
from the central block.Pictures were taken by Anders and Pierre.
After the disection the target was placed back in a can under argon. Any small piece were placed in a zip lock bag and also put in the can under |

UCx#3 was packaged into a spent can, double bagged and the bag and cans filled with argon as much as possible. Lid was attached and can moved to the
storage vault. The target was placed in in Pail 93, and placed into slot 1C of the vault, it was 11.7mSv/hr when removed from the south hot cell. See attached
file for latest vault details |

TM1 moved to conditioning station to today. After moving, I connected the vacuum system which include all gauges ,vacuum lines , controllers,and fans.I
started roughing the station through two turbo pumps(on TM1) . After 2 hours roughing, the station vacuum went to 100 mtorr. I started TP1 and TP2 on TM1
and turned on 3 gauges (png1 on service cap, ig1 on service cap ,and png4 on emittance box) . All turbo pumps and high vacuum gauges work fine .The |

|
A high voltage test was completed on a target free TM1 in the conditioning station. Only the turbo pumps on the target module were operational
due to phase 2 construction. Testing started at 2:51PM with the following vacuum gauge readings, 1.6 x 10^-6 Diagnostics Box, 7.4 x 10^-7 Service Cap,
2.0 x 10^-6 Containment Box. Voltage was increased ~3kV at a time every minute until 21 kV was reached with a current of 0 uA. Voltage was then increased |

|
Nb#6 has been inserted into the south hot cell in preparation for ionstallation onto TM1. During the pre-insertion inspection I noticed that I could
see the foil installed into the ionizer tube and that in did not seem to be seated or concentric to the tube itself. I had Anders and Friedhelm check this
and they deemed that it was ok. |

|
TM#1 moved from conditioning station to the south hot cell, the module had a field of 16mSv/hr. The move was not without excitement as the crane
decided on its own to move 2 inches west on two occasions during the move.On the second time that the errant moved happened I hit the E-stop on the crane
kill the power, the first time it happen it stopped the errant movement on its own. |

|
Chad and I did a leak check on TM1 Nb5 target heat shield circuit. The leak detector was connected to heat shield circuit.The pumping down of the
circuit is very smooth.Base leak rate is 0.0xE-9atm.cc/sec,and the base pressure is 0.0xE-4 torr. Chad checked the helium flow downstairs .He sprayed helium
to both up and down VCR joints 2seconds each time. There is no any response on leak detector(30 seconds waiting time). Both joints did the same test twice, |
