Observations and interpretation of energetic particle-driven ion cyclotron emission from JET DT plasmas
Ion cyclotron emission (ICE) excited by collective instability of fusion alpha-particles has been observed during deuterium-tritium experiments with radio-frequency heating and neutral beam injection (NBI) in JET. A model based on classical alpha-particle confinement is broadly consistent with this data. ICE spectra from discharges with high power NBI also show evidence of ion hybrid wave excitation by beam ions, relevant to alpha-channelling.
