RESISTIVE ALFVEN SPECTRUM OF TOKAMAK-LIKE CONFIGURATIONS IN STRAIGHT CYLINDRICAL GEOMETRY
The resistive Alfven spectrum for tokamak-like configurations with one or two singular surfaces is analyzed by combined WKBJ treatment and numerical solution using a spectral code. It is found that the ideal continua disappear; these are approximated only at the end points at the singular surfaces, and at selected interior points (given by extrema of omega-A(r) = /k.B-o//po-). The normal modes are damped and the eigenvalues lie on specific curves that become independent of resistivity for small eta.
