|
TM#3 electrical check at the south hot cell with no target to give us a base line and show that things are ok with the module for the start of
the running year. |

Friday, April 04, 2014, 14:59, Keith C Ng, ITE, Maintenance, , , measurement of new beam tube section
|
R. Kuramoto and A. Laxdal measured the distance from the 2A tunnel to the tank flange of ITE. The new fabricated beam pipe with bellows was used to gauge
the distance to the tank flange; The flange face of the beam tube was butted up to the tank flange and the beam tube was marked at the plane of the wall.
A metal rod was used to gauge the distance to the tank face using the same method. |

|
TM4 with Ta#42 was HV conditioned to 35kV with the optics tray at 17.5kV. There was some vacuum response while ramping but well within normal.
Attached is a screen shot and the associated data. |

Wednesday, March 26, 2014, 06:57, David Wang, South Hot-Cell, Standard Operation, TM4, Ta#42, Leak check on TM4 HS water line with new Ta #42 target.
|
Chad and I leak checked TM4 HS line with Ta#42 target on the module. The leak detector base LR 0.0xE-9 atm.cc/sec, base pressure0.0xE-4 torr. Chad applied
helium to the joints, and flushed the helium around the target. No leak has been found.I will do helium pressure test on this circuit at CS later. |

Tuesday, March 25, 2014, 09:11, chad fisher, South Hot-Cell, Standard Operation, TM4, Ta#42, Ta#42 install and "new" 9 pin
|
Ta#42 has been installed onto TM4. The "new" 9 pin connector was not an issue...attually went on better than any other previous one. Leaving
the mounting screws loose on the target half allowed use of the manipulator to center the pins and insert them with ease. |

|
Today:
1) Cleaned flange with methanol and cotton glove, appears to be clean.

Wednesday, March 19, 2014, 16:48, Keith C Ng, ITE, Repair, , , 2a3 window - beam tube removal 11x
|
Today:
1) Vaccumed top and around clamp. Disconnected clamp from flanges and removed from beam line. Currently bagged and stored in metal pail next to
target pit area. Clamp is 500 µSv @ 1/2 m. |

Wednesday, March 19, 2014, 15:46, David Wang, ITW, Standard Operation, TM4, , TM4 and ITE air to vacuum leak check and TM4 water lines helium test. 7x
|
With TM4 located in ITW, All air to vacuum seals on ITW primary and secondary vacuum vessels have been leak checked with leak detector
hooked directly onto the TM4 service cap.The base LR :00xE-9atm.cc/sec. The ITW IG1 was 1.16xE-6 torr which was good. No leak has been found during the
checking.Also, the TM4 water lines(except HS) had been pressurized with 70 psi helium on each for 2 minutes. There was no response during the test. |

Tuesday, March 18, 2014, 16:01, Keith C Ng, ITE, Repair, , , 2a3 window - prep and clean
|
Continued with vacuuming inside wall penetration to remove debris. Changed filter bag in nilfisk vacuum, left old filter in place however vacuum continues
to stall after >5min use. Vacuum gets quite warm before self shutting off. Debris seems to be falling back down on to joint if vacuum is turned off.
Took some screenshots of video showing removed debris and rust(?) on beam pipe. Video located on remote handling group folder. |

Monday, March 17, 2014, 15:39, Keith C Ng, ITE, Repair, , , 2a3 window - prep and clean
|
Cleaned top of the ITE vacuum flange and top of window clamp. Attempted to clean the bellows/beam pipe through the wall, mostly dust and small particles.
When cleaning bottom of the wall penetration we picked up a stone/fragment and the vacuum stopped. Appears to be a rock of some kind. 800cpm.
Videos on \\trwindata\groups\remote handling\Videos\2014\2014_2A3window folder, videos 3 and 4. |
