Title: NUMERICAL CALCULATIONS ON REVERSED FIELD HEATING IN THE THETATRON

Abstract

Numerical solutions of the two-fluid hydromagnetic equations designed to study the effect of trapped magnetic fields on the properties of a plasma compressed in the theta are discussed. Conditions typical of the AWRE Maggi condenser banks were selected: deuterium at an initial pressure of lOO mu contained in a tube 4 cm in diameter is compressed by a field rising to 100 kilogauss in 2.5 mu sec. Initial bias fields of between +5 and --5 kilogauss were used, and the effects of preheat and rate of compression were assessed. The calculations showed that rapid joule heating is niaintained by the large field gradients characteristic of reversed field discharges, and for an initial bias field of --5 kg a peak electron temperature of 1.3 kev was predicted.
