Trapped electron mode in a quasi-isodynamic stellarator

Trapped electron mode in a quasi-isodynamic stellarator

Global gyrokinetic simulations find a strongly unstable trapped electron mode excited by a density gradient in a quasi-isodynamic stellarator. The eigenmode structure localizes on the inner side of the torus with an unfavorable magnetic curvature and weak magnetic field, where there is a large fract...
