|
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. |

|
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. |

Monday, April 16, 2012, 16:17, Bevan Moss, Conditioning Station, Standard Operation, TM1, No Target, High Voltage Test
|
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 |

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 |

|
I did a leak check on conditioning station vacuum system today.The vacuum system had been roughed over night . This morning before the leak check,the
convectron gauge reading on emittance box is 20m torr which is reasonable. I hooked the leak detector to system (without turbo pump on)
. The leak detector showed base LR 6.3xE-8 atm.cc/sec. At this base LR, I found 2 leaks up to low E -6range on that cross tube flange to small turbo pump, |

I pumped down conditioning station IMC today. The inside bellow pressure is -20 psi on the gauge.Visually checked the bellow before and after pump.The
bellow is in retracted condition now. |

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 |

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. |

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:

I had changed all old induction coils for flow sensors in ITE .I checked all ITE water signals on control boards in electrical room.They are all very
stable and constant.All ITE inductions coils work fine now. |

TP2 on TM4 has been replaced with a new turbo pump , I didnt reset the controller in electrical room.So this new pump start to run at 8083 hours
on ITE TP2 controller. The new TP2 pump properly started. It works fine now. |

|
All targets in the mini storage have been moved to F-308s and those flasks have been moved over to rad waste. The transfer of target occurred on January
10th and the flasks were moved to rad waste on January 11th. Contamination was found on the bottoms of some of the pails and was removed, some of
the contamination was difficult but not impossible to remove from the pail bottoms. |

Hi Remote Handling,
The guage on the IMC circuit in the Target Hall is reading atmosphere, and the bellows is currently relaxed (i.e. expanded), whereas it should
be reading about -20inHg and the bellows should be contracted (i.e. compressed). |
