Abstract

The experimental identification of the physical mechanisms behind the rotating magnetic helical modes with low numbers m,n which appear at magnetic surfaces where q = m/n is an elusive task. We discuss here a theoretical principle of a combined analysis of magnetic Mirnov signals and of electron cyclotron emission signals that can shed light on the underlying physics of these perturbations.
