|
David and I checked circuits p and q (the water cooled coil ciruit) for flow this morning as, with the source tray still in the module, there was both
a leak and a leak tight blockage. Both p and q allowed air flow through them confirming that the blockage was in the surce tray side of the system.
The heat shield circuit was also tested for flow and it passed. |

The source tray has sucessfully been removed from TM3.
I will put a report in the TM3 rev 3 docushare directory as there were some items of note during this procedure. |

|
Chad removed the source tray from TM3 today, see attached picture (video was also taken). There was some interference between the window cooling
lines and the frame work as well as the clamps for the ground electrode and the water block alignment jig. There was also interference between the optics
alignment post (specifically the mushroom top) and the water block alignment jig. Investigation into these inferences needs to be completed as they could |

|
Service tray side of the waterblock jig is installed and all locking tabs enagaed save the heat shield circuit. Locking tab for heat shield circuit with
be worked on Monday morning and installation of the source tray side of the waterblock jig should commence on monday as well. |

Friday, April 26, 2013, 11:20, chad fisher, South Hot-Cell, Repair, TM3, , Water Block Jig (back half)
|
The back half of the water block jig (services tray side) has been sucessfully located onto the module.
About 50% of the waterblocks have centered themselfs it their respective cups and the rest look good for concentricity but will require some gentle
wiggling to get them to seat. |

|
Optics tray has been removed from module.
Waterblock jig installation has commenced. Of note, jig installation on TM3 has proven more dificult than the previous installation on TM2. Many
of the waterblock assemblies are skewed (not perpendicular to plane that they should be...perpendicular to). |

Wednesday, April 24, 2013, 09:00, Bevan Moss, Conditioning Station, Development, , , New user testing
|
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. |

Tuesday, April 23, 2013, 16:11, Bevan Moss, Conditioning Station, Maintenance, TM3, N/A, Chiller Fault 2
|
During Testing it was noticed that Fault 2 was indicated and one of the compressors would not run. Fault 2 does not indicate what the issue was
and during inspection nothing could be detected. It had something to do with TCS:CHILCP3 and possibly CP2. CP1 could still be operated and was controlled
manually to keep the temperature in the correct range. This was not required but it does affect the conductivity. The main power switch on the chiller |

Tuesday, April 23, 2013, 15:52, Bevan Moss, Conditioning Station, Standard Operation, TM3, N/A, Further HV Testing
|
Further HV testing was completed today from ~2:00 until 3:00. The resistivity of the water was 11.7 - 12.7 Mohm. The EE was turned on to 1500 V
and had a leakage current of 1.465 mA with a inline and ballast resister of 20 kohm and 1 Mohm respectively. In addition to this all of the CB were turned
on to 500V. The voltage on the source tray with all bias items tied together and the voltage was then raised to 30kV in 5kV steps. It was then raised until |

Monday, April 22, 2013, 11:35, Bevan Moss, Conditioning Station, Repair, TM3, N/A, TCS:DIF2 broken
|
The flow meter on the primary side (TCS:DIF2) of the conditioning station is broken. I investigated and there is flow, the gauge is not fouled,
and the PLC does read back when current supplied. The gauge is also reciving 24V but the output is 0V and 0mA. I will contact ESC and the supplier. |

|
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 |
