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.
