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 |

|
UCx#38 developed a short between the plasma electrode and the extraction electrode about 30mins after reaching full temperature in the conditioning station.
The decision was made to bring it into the anteroom and try to clean it there.
To do this, it was uninstalled, the parasitic attachments were removed and it was brought into the ante room. |
