|
TM4 with CS Test Target #1 was moved from the SHC to the Conditioning Station. All went well. The welding cables came a little close to the cage,
David will bend them in more in the future. |

|
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. |

Wednesday, March 13, 2013, 11:23, chad fisher, South Hot-Cell, Repair, TM4, , Ground Electrode Leak
|
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. |

|
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 |

|
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. |

Today David and I moved the module from ITE to the SHC. Move went very smoothly, David operated the cameras and has had basic training in how to
manually lock out the controls. |

|
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 |

|
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 |

Friday, February 22, 2013, 13:13, Bevan Moss, Conditioning Station, Development, TM4, CS Test Target #1, Broken Turbo Pump
|
Today while putting the cover on the cord that goes to the controller was bumped. This bent the connector down and caused a vacuum leak. I tried
to tighten the bolts in the hope the leak would go away but it did not and I sheared one of the bolts off. David is inquiring with Edi if the pump can
be repaired or if it needs to be replaced. The good news is that the interlocks work exactly as planned. Upon detecting a leak they shut the turbos down |

Edi and I replaced the broken ITH MP1 in target hall with a new pump. The old pump was leak on oil. There were no oil had been left in the old pump by
checking the sight glass.Thats the reason of the pump failure.The tray which the old pump sat on was full of leaking oil ( highly contaminated
). The old pump was bagged in 3 thick plastic bags ,and the tray was cleaned before the new pump was installed. The working area had been cleaned up and |

Wednesday, February 06, 2013, 14:34, Bevan Moss, Conditioning Station, Development, TM4, CS Test Target #1, 40kV All Common w/o Water Test
|
Today the module was biased to 40kV in the conditioning station. The current draw was 0uA. Sparking started at 27 kV. I have attached the recording
from the strip tool of the vacuum while we were testing. After consulting Pierre if we should take the module to a higher voltage it was decided not to.
The purpose of this test we to check the interaction between the module, cover, new cooling line, EE and EINZEL cables. This test was considered a success |
