Context. Spectroscopic observations and theoretical models suggest resonant wave-particle interactions, involving high-frequency ion-cyclotron waves, as the principal mechanism for heating and accelerating ions in the open coronal holes. However, the mechanism responsible for the generation of the ion-cyclotron waves remains unclear. One possible scenario is that ion beams originating from smal...

Abstract The prediction of plasma rotation is high interest for fusion research due to the effects upon magnetohydrodynamic (MHD) instabilities, impurities, and turbulent transport in general. In this work, an analysis method was studied validated reliably extract momentum coefficients from neutral beam injection (NBI) modulation experiments. To end, a set discharges created with similar backgr...
