Preliminary finding
05-26-2010 @ 15:45: The oven was at 100C. The ion pump readings were good. We reset the oven temp to 150c.During the rise in oven temperature the Ion pump that is connected to power supply 10B trip a breaker from high current draw. We tried to reset the power supply, the power supply would not reset. The oven was then turned off so we could troubleshoot the situation.
05-27-2010 @ 08:00: After some testing, it appeared that the high voltage cable going to 10B was shorted. The shielding had come in contact with the center conductor where it was clamped for strain relief. We replaced the cable. The ion pumps where all working again.
At 16:30 we put the couplers back into the oven, connected the nitrogen purge. And purged the system over night.
05-28-2010@ 09:00: The oven was restarted and set to 100C. At 14:00 the oven was set to 150C.
05-30-2010@ 13:30:The bake out was completed and the oven was turned off.
