Comparison of methods for numerical calculation of continuum damping

Bowden, George; Könies, Axel; Hole, Matthew; Gorelenkov, Nikolai; Dennis, Graham

Description

Continuum resonance damping is an important factor in determining the stability of certain global modes in fusion plasmas. A number of analytic and numerical approaches have been developed to compute this damping, particularly in the case of the toroidicity-induced shear Alfven eigenmode. This paper compares results obtained using an analytical perturbative approach with those found using resistive and complex contour numerical approaches. It is found that the perturbative method does not...[Show more]
