AC STABILIZED THETA PINCH
Abstract
Attempts to produce dynamic stabilization of the plasma column in the Physical Research Laboratory's theta-pinc experiment by means of an rf azimuthal magnetic field are described. The rf currents used were produced by the damped oscillatory discharge of high-voltage capacitors through the inductance of the plasma column. The maximum rf current (at the end of the first half cycle) was 13,900 amperes at 2.5 megacycles. No evidence of stabilization was obtained. A pulsed 1-megawatt vacuum-tube oscillator, designed to produce an undamped rf current, is being constructed. Spectrographic investigati n f the continuum intensity, the variation of the continuum intensity with wavelength, and the Stark broadening of the D/beta Balmer line have yielded values for the electron temperature and the electron (ion) density.
