Kinetic and finite beta effects on the m=1 tearing instability
Journal Article
·
· Phys. Fluids; (United States)
Tearing instabilities with poloidal mode number m=1 are examined by means of a kinetic description of the electron response. At very low beta, the use of a frequency dependent Ohm's law permits investigation of colllisionless regimes, and new modes are found. At finite beta, variational solution of the eigenmode equation shows that one of these modes remains unstable for quite large beta.
