Dynamics and dependencies of the configuration-dependent 1–2 kHz fluctuation in W7-X

A 1–2 kHz electromagnetic mode is present in a large fraction of W7-X discharges in the standard magnetic field configurations with 5/5 edge island structure. The power in the mode is significantly reduced in other magnetic configurations. The mode can appear spontaneously and persist for the full d...
