THE HELICAL INSTABILITY OF THE PLASMA COLUMN WITH A FINITE AMPLITUDE,

Abstract

The helical stability of the plasma column in a longitudinal magnetic field is investigated using the macroscopic equations of motion and continuity for ions and electrons. The results are combined with the energy balance equations for the positive column in order to determine the longi tudinal electric field as a function of the applied magnetic field. The frequency of the helix is calculated as a function of the applied magnetic field and compared with the experimental findings. The internal magnetic field of the helix is also calculated as a function of the applied magnetic field. It is found that the positive column is paramagnetic when the neutral gas pressure exceeds a certain value and the applied magnetic field is increased. (Author)
