Module: TM3 
Target/Number: No source tray 
Subject: HV test repeat 

 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 minutes until once again the water resistivity sensor tripped again. It appears that there is a~ 44kV limit on TM3. Attached is the data. I will present all of the data to the group tomorrow showing the results of multiple testing.
