|
I did a 5KV mega test on TM3. Only5Mohm @5kV between coli line PQ and chassis(ground). It confirmed the close gap between P,Q and GE. Other lines
are ok. See attachment. |

|
Last Friday July-15, TM3 was leak checked at TCS. All air to vacuum seals on service cap are good. Helium pressure test on TM3 water lines(except
GE, HS, and Window) were done. Leak detector has no response at 0.0xE-9 atm.cc/sec. They are leak free. |

I started vacuum system.
I started TCS water system. The chiller does not work properly still. But, It will not affect the TM3 HV conditioning. HV cover is installed
on TM3 in TH. The module is ready for HV conditioning. |

Requested by Aurelia, and approved by Friedhelm, TM3 service tray cover plate ITA2108 has been remove out of the module. The plated is checked for active
and contamination after removal. Then,It is double bagged, sealed , tagged, and placed downstairs in TH between south wall and green block . The
ram contact reading on the plate is about 10 usv/hr. We will do anther TM3 HV test at TCS without this cover plate. |

All TM3 blue insulators except Gas,EL, and 60 KV common on top of the module have been replaced with new designed insulators. The new blue insulator
for gas line need to be modified to fit for the bent on the gas line. EL, and 60KV common blue insulators were replaced during last time
TM3 refurbishment so they are relative new, and not replaced this time. All seals related to the blue insulators are changed to new seals. The o- |

Monday, September 12, 2016, 09:25, David Wang, Conditioning Station, Repair, TM3, , TM3 leak checked at TCS
|
After blue insulators replacement, TM3 service cap are leak checked. LD base leak rate 0.0xe-9 atm.cc/sec. I sprayed lots helium on all blue insulator
seals. No leak has been found. Double checked them again, and got same result. All other seals on top of TM3 also have been checked. They are leak free.
OVEN, TUBE, MSP, COIL, and EE water lines are pressurized with 70 psi helium for 3minutes each. They are good also. |
