Low frequency m = 1 modes during standard and improved confinement scenarios in W7-X

Low frequency m = 1 modes during standard and improved confinement scenarios in W7-X

In the Wendelstein 7-X stellarator (W7-X), two related global low-frequency electromagnetic oscillations are observed on many diagnostic systems (e.g. plasma stored energy, Mirnov coils, Langmuir probes, etc). The activity is related to the presence of magnetic islands at certain radii. However, in...
