Pulsed Plasma Loss and Acceleration Mechanisms in Strong Bias Magnetic Fields.

Abstract

Results of the first year of a study of plasma acceleration in the presence of a strong applied bias magnetic field are described. A theoretical model has shown that acceleration efficiency is limited to 50% for a constant field strength. However, it can be increased to more than 80% by applying a bias field that decreases in the direction of acceleration. Experiments with argon in an accelerator of this type are described which show an acceleration efficiency increasing with 1sp to a value of 80% at 2000 seconds 1sp Steady Gas flow was used for the experiments with current supplied for 0.8 m sec from a pulse line. Impulse was indicated by the deflection of the bias field magnet which was suspended as an impulse pendulum. (Author)
