Wednesday, March 02, 2016, 10:04, David Wang, ITW, Standard Operation, TM2, , Leak check on ITW and TM2.
|
Dan and I leak checked TM2 and ITW primary vacuum vessel. It was found a 1X E-7 atm.cc/sec leak on top T flange seal between TM2 and dump module in first
time check. But it is not a repeatable leak. I checked the same spot and around area two more times with increased helium volume.It did not show up again.
The first response could be a helium drift to dry scroll pump. I will check it again later. The primar vacuum vessel on ITW and TM2 are leak free. |

Friday, March 04, 2016, 12:34, David Wang, ITE, Standard Operation, TM4, , TM4 ITE annual leak check
|
Dan and I finished TM4 and ITE annual leak check on primary and secondary vacuum vessel. We found one leak on a KF25 blank off which is located
on the top of the service cap. It is a low E-7 atm.cc/sec range leak. But, it is very close to turbo-pumps so ITE IG1 and other gauges are not affected
by it very much. It is an easy fix. TheKF -25 center ring on the blank off will be replaced after vent . It be will leak checked again at CS |

|
Two of resin tank filter cartridges(supply and return) are changed today. Old cartridges and bagged and tagged. The contact field on them are 650usv/hr.
The new cartridges are fiber-glass, Triumf store item. After replacement, the field on contact with the filter case are about 10 usv/hr. But the field
on contact with top resin tank has been increased from 45usv/hr to 225 usv/hr |

Chad and I finished the first round check on Tm2 water lines. The lines and spots checked are: Target oven + and - (front side braze joints) , Tube
heater+and -(front side braze joints and water blocks), coil2 and coil 1(front side braze joints and area close to water blocks),. No leak has been found
on all above of them. The last, we checked the GE which has the biggest leak so far. The leak detector base leak rate only can get |
