Interpretation of ion cyclotron emission from sub-Alfvénic fusion products in the Tokamak Fusion Test ReactorFunded under: EAEC-FUSION 12C
Ion cyclotron emission (ICE) has been observed during neutral beam-heated supershot discharges in the Tokamak Fusion Test Reactor (TFTR) deuterium-tritium campaign at sequential cyclotron harmonics of both fusion products and beam ions. In this paper it is shown that the magnetoacoustic cyclotron instability which results in the generation of obliquely propagating fast Alfvén waves at low cyclotron harmonics of the fusion ions, can occur under such conditions. Moreover, the time evolution of the maximum growth rate closely follows the observed time evolution of ICE amplitude, averaged over several TFTR supershot discharges.
