Behaviour of a toroidal plasma in a rotating magnetic field
Abstract
Preliminary results are reported for an experiment in which an argon plasma was contained in a toroidal system by means of a steady toroidal magnetic field in combination with a rotating transverse two-pole magnetic field. The theory of rotating-field plasma confinement is outlined, and the experimental system is described in detail. Stable compression was observed at low rotating-field strengths. But, at field strengths exceeding the critical value of approximately 0.8 mT, rapid plasma heating occurred and the density reached a value corresponding to nearly complete ionization. Little compression was observed in this case and is attributed to anomalous resistivity.
