Friday, April 11, 2014, 11:35, David Wang, Conditioning Station, Standard Operation, TM3, , Helium pressure test on TM3 HS water line with new Ta target. at CS 6x
|
| The helium pressure test on TM3 HS water line with new Ta target is finished at CS. The circuit is leak tight.. No any response on LD. See pictures. |

Thursday, April 10, 2014, 14:03, Bevan Moss, Conditioning Station, Standard Operation, TM3, TiC#4, HV conditioning
|
The TiC#4 target that is on TM3 was conditioned to 25kV today with the EINZEL lens at 12.5kV. There was one spark shortly after reaching 25kV that
reset the bias PS and another one after the module sat at 25kV for ~30 minutes. Attached is the strip tool data and screen shot. Prior to starting
the conditioning the power on the chiller needed to by cycled as the VFD on the fans had tripped due to a recurring inrush problem. |

Wednesday, April 09, 2014, 11:10, David Wang, South Hot-Cell, Standard Operation, TM3, , TM3 heat shield circuit leack check at SHC
|
This Monday morning, Chad and I leak checked heat shielding circuit on TM3 with new target installed. The base LR on LD :0.0xE-9 atm.cc/sec, base pressure
0.0xE-4 torr. Chad sprayed helium twice on the VCR joints. No leak has been found. The circuit will be pressured with helium at CS. |

Monday, April 07, 2014, 10:48, Travis Cave, South Hot-Cell, Standard Operation, TM3, no target, Electrical check
|
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. |

Monday, March 31, 2014, 13:22, Bevan Moss, Conditioning Station, Standard Operation, TM4, Ta #42, HV conditioning
|
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. |
