|
I have inserted the test target for TM4 and the CS into the hot cell.
I had some concerns about the condition of the target which I have discussed with Pierre and he has cleared. Pictures are attached. |

|
Bevan attempted to start pumping down on TM4 today remotely but there was an issue. He will report on Monday.
I went into the Target Hall this afternoon while on the phone with Bevan and performed the following:
- Checked the knurled vent valves on the side of each turbo, both were found to be in the tightened position (all the way clockwise) |

2013 winter shut down ITW-TM1 primary vacuum vessel, secondary vacuum vessel, and water lines leak check: connected leak detector to TP2(primary and
water lines) and TP4S (secondary). base leak rate 0.0xE-9atm.cc/sec,base pressure 0.0XE-4torr. Sprayed helium to all primary vacuum seal and there is no
response on leak detector. Helium pressurized all water lines(except HS) at 70psi ,3mins.Tube heat(+) no response, tube heater(-)1.6xe-9atm.cc/sec, target |

|
the switches and the solenoid are all wire up to 24VDC, when you open either of the little doors the solenoid switches this is also true if there is
a power loss. currently the solenoid is powered. |

|
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 |

|
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 |

Tuesday, March 12, 2013, 09:18, chad fisher, South Hot-Cell, Repair, TM4, , Ground Electrode Leak
|
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. |
