Abstract :
Summary form only given. We have studied anode heating in Gamble II rod-pinch experiments as a means of eliminating the proton component of the anode plasma. The rod is isolated with a small flashover switch and biased to 4-6 kV. Electrons from a nearby filament then heat the rod to about 2000 K for several minutes prior to and during the shot. Carbon activation measurements indicate that the proton component of the ion beam is effectively removed.
