|
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 |

|
To confirm that the sparking was coming from the module rather than the conditioning station TM3 was grounded and the conditioning station biased.
Attached are the results. Highlights include that there was no sparking and the station was able to achieve 60kV (limited by controls from going higher).
The current from the raw file has been corrected by the required factor of 5. |

|
After discussion with Friedhelm it was decided to continue trying to condition the module today before moving it tomorrow. The voltage was quickly
raised until 40 kV where it was left for ~30 minutes. Sparking was minimal. It was then slowly raised to 44.3 kV it held this voltage for ~8 minutes when
the current started to climb (remained below 200uA as set as a limit in previous tesing). There was also sparking at this point. This continued for ~2.5 |

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 inspected the service tray water block and suggest that they SHOULD be cleaned/polished before we install the new source tray.
The water blocks have slight water scalling to the inside of the ID of where the c seals locate.
I have taken two close up pictures of each water block for reference and to document their current state. They can be found at http://documents.triumf.ca/docushare/dsweb/View/Collection-10841 |
