Carla did the test. and reported the result as following: HV testing of ITW is complete. It was pretty well behaved up to 59.5kV, and sat at 59kV for 30mins with no sparks (that EPICS caught). There was some strange behaviour of the current between 51kV and 53kV - it was jumping by 20uA or more - but there didn't seem to be any voltage response, and it went away after 53kV (though it returned on the way back down). The test was done in Feb 02.
