Effect of the Toroidal Asymmetry on the Structure of TAE Modes in Stellarators

Abstract

It was found recently with the use of the ballooning formalism that the toroidal asymmetry of the stellarator magnetic configuration can significantly change the structure of Torodicity-induced Alfvén Eigenmodes (TAE) with high toroidal mode numbers (n), producing singular (stepwise) wave functions [Yakovenko, Yu.V., et al., Energetic Particles in Magnetic… (More)
