Kink macroinstabilities and resistive layer structure of internal kinks in cylindrical plasma
Eigen-frequencies and shapes of the non-local magnetic kink-modes m=1, n>1 in a field reversal pinch are obtained in cylindrical force-free approximation by shooting method. The mode profile and the resistive layer containing the resonant surface of the internal kinks are calculated numerically...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Summary: | Eigen-frequencies and shapes of the non-local magnetic kink-modes m=1, n>1 in a field reversal pinch are obtained
in cylindrical force-free approximation by shooting method. The mode profile and the resistive layer containing the
resonant surface of the internal kinks are calculated numerically. Instability is revealed, both for external and internal
modes, which is not effected by resistive layer in plasmas with high conductivity, it is determined by the current
gradient due to the high paramagnetic parameter in the pinch core. |
