Friday, March 01, 2013, 11:35, David Wang, ITE, Maintenance, TM4, , Leak check on ITE and TM4.
|
The leak check on TM4 and ITE is done. All primary vacuum vessel , secondary vacuum
vessel on TM4 and ITE are leak tight. There is no any response had been found on leak detector(leak detector base LR 0.0xE-9 arm.cc/sec). All water
lines had been pressurized to 70 psi helium for 3 minutes. They are all perfect leak tight( I cant find even a tiny response on leak detector) except |

|
ITW EXIT1 o-ring replacement is fininshed today. The ITW EXIT 1 is back to ITW.
The old o-ring lost most its elastic property and changed to stiff sqaure shape inside the slot.The flange surface around the o-ring slot was dirty.
I cleaned the o-ring surface completely before putting the new o-ring . Everything should be fine now. There will be a leak check late |

|
On Monday, March 11 the containment box was removed from TM4 and a vacuum leak check preformed in an attempt to locate the leak in the ground electrode
circuit.
Following Pierre's work plain helium was sprayed was the highest joint accessible towards the lowest. |

|
Further attempts to localize the leak were unsucessful. The circuit was pressurized with 60 psi air and snoop solution was applied to both the braze
joints and the mating surface between the two halfs of the water blocks. Unfortunately, no visible bubbles could be dectected.
This was reported to Grant and Pierre and it was decided to continue with removing one of the vcr gaskets from the optics cooling lines (on the |

|
The containment box has been re-installed and the window waterlines reconnected and leak checked.
The window lines did pass the leak check, however the leak dectoctor did not pump down past 5.8 x 10-9.
The front cover has also been reinstalled. |

|
Dave Morris and I investigated the Faraday Cup today. It was found to be plumed in the wrong direction (fails in). This is not an issue for the
conditioning station as there is nothing down stream from the cup. Dave will change the controls to reflect this. |

Thursday, March 14, 2013, 07:18, David Wang, South Hot-Cell, Standard Operation, TM4, , TM4 window cooling line leak check
|
It took a long time(more than 1 hour) to pump down the TM4 window cooling line during leak check time. The base leak rate could only be
pumped to 5.8xE-9 atm.cc/sec.Base pressure is 0.0xE-4 torr which is bottom reading. Chad and i did the leak check at this base leak rate .No leak had been
found. The window cooling line is leak tight at this stage. A pressure helium test will be fulfilled in conditioning station on this cooling line later. |

Wednesday, March 20, 2013, 08:19, David Wang, Conditioning Station, Repair, TM4, , Leak check new installed TM4 TP1 at conditioning station.
|
I leak checked new installed TM4 TP1 at conditioning station. The CS vacuum gauges reading were at 1.0-1.5xE-6 torr . Leak detector base leak rate 0.0xe-9atm.cc/sec,
base pressure 0.0xe-4torr. I sprayed helium around the pump inlet flange and KF 25 pump outlet flange to pump joint. There is no response on leak
detector. The new installed TP1 is leak tight. |

|
I leak checked new installed ITW EXIT1 tank to module o-ring.No leak had been found . Also ,TM1 primary vessel air to vacuum seals had been checked at
the same time. There was no response had been found on leak detector. |

|
TM3 leak check at conditioning station without target: TM3 all air to vacuum seals have been leak checked . They are all good. Water lines TAR(+-), TUBE(+-),
GAS, MSP , COIL2(+-), EE, HS(1,2) , GE,and WINDOW have been helium pressurized to 70 psi for 2 minutes each . No response had been found on leak detector.
They are leak tight.. Leak detector BR 0.0xE-9atm.cc/sec, BP 0.0xE-4 torr. TM3 and CS vacuum: PNG15.2xE-6 torr, IG1 8.8xE-7 torr,IG2 2.8xE-6torr, IG1S |

|
Controls has created a new user group that can operate the conditioning station but cannot use any of the bypasses or forces. The cooling package
will be used to test this new profile. The main loop bypass has been opened to allow this testing to happen without the risk of over pressure. |
