THE RESISTIVE ALFVEN SPECTRUM OF TOKAMAK-LIKE CONFIGURATIONS
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-ALPHA(tau) = /kappa.B-omicron//square root of rho-omicron). The normal modes are damped and the eigenvalues lie on specific curves which become independent of resistivity for small eta.
