September 24
After the manipulator repair Maico installed the NiO#2 onto the target module. Once connected I completed a leak test on the HS line with
Isaac. The leak testing cart would not pump down originally (something wrong with the cart) but eventually it did start to work. The cart pumped to its |

|
The water pumps for the conditioning station were turned on at ~11:45. It took longer to start the conditioning station as the air from the leak
test had to be bled off and the make up water tank refilled. The valves on the water supply line were closed slightly to make up for the fact the water
cooled power supply has been removed. DIF2 was installed by Maico so we can measure the flow in the primary side. |

|
The first attempt at HV conditioning of TM3 with the new source tray and NiO#2 target installed. Conditioning so far has been very slow, with the
current increasing quickly to a maximum of 400uA. Voltage in these cases was lowered until the current was below 200uA. Attached is the raw data. It appears
the source tray and target are conditioning just there is either something burning off or there is localized poor vacuum. |

Thursday, September 26, 2013, 15:00, Bevan Moss, Conditioning Station, Standard Operation, TM3, NiO#2, RGA not connecting
|
Following the helium pressure test Don attempted to connect to the RGA via the network. He was unable to do so. This scan was desired so a pre
and post water scan could be compared to indicate if there was any leaking. It has been decided to carry on as the HV and HP tests are of greater importance.
Don will continue to investigate the RGA. Travis inspected from the conditioning station roof and determined that the RGA is getting power. |

Friday, September 27, 2013, 12:53, Bevan Moss, Conditioning Station, Standard Operation, TM3, NiO#2, HP TGHT and TBHT conditioning
|
Yesterday TM3 had the TGHT current raised to 160 amps and the TBHT raised to 200 amps. At this power the TGHT showed typical results in that vacuum
was affected and the increased voltage as the target increased in temperature. The tube heater on the other hand did not change voltage or show a change
in vacuum. As a result it is believe there is a short somewhere in the module. I have attached a screen shot of the strip tool and the raw data. |

| The roughing pump for TCS was started at ~3:00 and the turbo's turned on at ~4:00. This is the minimum time for the module to pump down. |

|
The filament on IG1 for TM3 was replaced by myself and Edi. The old filament did not appear to be damaged but the controller claimed it was. The
current gauge on TM3 is a single filament, ideally it would be upgraded to a double. |

Yesterday the TBHT was ramped to 250 amp and the TGHT was ramped to 440 amps. Attached is the data from that run the strip tool that had this screen
shot crashed but it can be recreated with the data. The TBHT ps was not reading back accurate results as such there are large steps in current or voltage
or some instability for no apparent reason. In addition to this the ramping program is still not working so the ramping was a very manual process. The |
