Wednesday, May 15, 2013, 10:17, Bevan Moss, Conditioning Station, Standard Operation, TM3, No Source Tray, Preliminary Results from HV testing 
|
Testing on TM3 without a source tray was completed on 13/05.2013. All items were tied to common and the water blocks were left open at the bottom
of the module. They were left with the quick connections at the top. The vacuum was in the low 10^-6T range so this was deemed acceptable. The cooling
lines withing the cage in the target hall were shorted so flow could continue. As you will see from the results a maximum of 44kV was achieved before a |

Wednesday, May 15, 2013, 16:51, Bevan Moss, Conditioning Station, Standard Operation, TM3, No Source Tray, Repeat of HV Test
|
The HV test completed on Monday was repeated today over a much longer time period. By taking longer there was slightly less sparking but once again
a maximum voltage of ~44kV was achieved. The resistivity of the water was much higher during this run so the leakage current was less but still in
the >100 uA range. The spark that occurred during the ramp up to the maximum voltage caused the "water resistivity" limit to trip. This was |

Tuesday, May 21, 2013, 11:52, Bevan Moss, Conditioning Station, Standard Operation, TM3, No Source Tray, May 16th Long HV conditioning
|
On May 16th 2013 the module was HV conditioned all day. As a result the maximum stable voltage has been increased to about 47kV (~4kV more than last
test). A maximum voltage of 49kV was achieved but the module was very unstable. Attached is the data from the testing. Note that occasionally the sparking
caused the PS to reset, it was turned back on and the voltage increased back to what it was (or lower) quickly. |

I have fallen behind on the HV testing that has been completed on TM3. Data can be found on docushare in the TM3 Rev 3 folder files are
too large to attach. From the last elog entry the following tests have been completed
July 8 2013 - Long HV conditioning 50kV achieved before sparking caused PS to trip. Was unable to recover to the same voltage |

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. |

Thursday, September 26, 2013, 14:55, Bevan Moss, Conditioning Station, Standard Operation, TM3, NiO#2, HV conditioning
|
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. |
