|Replaced filament. Prior filament had 52 hours. Suspect user error setting current too high, however the filament was operating for most of its life at a very poor vacuum. Also changed out Weinhelt aperture with used spare. Old one needs to be cleaned and polished, not exactly sure how. Need to contact Susan (former operator.) At 10 kV, first peak at 2.61A, second peak at 2.86A. Also corrected connection of mist and odor filter to rotary vacuum pump, which was not properly seated.
