Stability of rotating plasma with twisted magnetic field. II

  • Published:
Zeitschrift für Physik

Abstract

The stability of a uniformly rotating cylindrical plasma configuration in dynamical equilibrium is discussed. Assuming an axial current and sheet currents for the plasma, we have obtained a dispersion relation for non-axisymmetric perturbations. The dispersion relation comes out to be a complex and implicit function of the frequency of perturbations. Here we have discussed the dispersion equation for the modem=1, with the help of numerical computations. It has been shown that rotation has a stabilizing influence, whereas the axial current destabilizes the cylinder.
