Observations of Alfvénic-character oscillations in ohmic plasmas on the COMPASS tokamak.
Original language description
In plasma magnetic confinement devices, a significant presence of superthermal Energetic Particles (EP) (e.g. from auxiliary plasma heating systems) can drive instabilities via resonance of particle velocity with plasma Alfvén velocity, which can in turn negatively affect the EP confinement. However, there have been reports of plasma Alfvén eigenmode oscillationsnin purely ohmically-heated plasmas on several experimental devices. In this paper we report observation of similar Alfvén eigenmode oscillations in ohmically heated plasmas on the COMPASS tokamak and classify them with respect to the reports from other devices from the perspective of mode frequency scaling, localization and possible excitation mechanisms.n
