MHD stability of runaway electron discharge in Tokamaks
Abstract
The influence of directed kinetic energy and anisotropic pressure associated with runaway electrons on toroidal stability properties was examined. A runaway electron current concentrating in the central region is shown to have stability effects on magnetohydrodynamic stability against kink and tearing modes, provided it is rigid and immobile. This supports a concept of axisymmetric toroidal plasma confined by a relativistic electron beam injection or another heating method.
