Interpretation of ion cyclotron emission in the HL-2A tokamak
Abstract We report the first interpretation of ion cyclotron emission (ICE) based on the frequency variation in HL-2A tokamak experiments. The measured frequencies of ICE are concentrated around the ion cyclotron frequency, while simultaneously exhibiting a linear scaling with the Alfvén velocity. A fully kinetic simulation demonstrates that with low fast ion concentration, ICE frequency approaches the fast Alfvén wave dispersion relation. The dispersion relation of ICE is similar to the dispersion relation of ‘equatorial noise’ in the inner magnetosphere, providing new opportunities for comparing physical model interdisciplinarity.
