Ion cyclotron emission (ICE) was the first collective radiative instability,driven by confined fusion-born ions, observed from deuterium-tritium plasmas inJET and TFTR. ICE comprises strongly suprathermal emission, which has spectralpeaks at multiple ion cyclotron harmonic frequencies as evaluated at the outermid-plane edge of tokamak plasmas. The measured intensity of ICE spectral peaksscaled linearly with measured fusion reactivity in JET. In other large tokamakplasmas, ICE is currently used as an indicator of fast ions physics. Theexcitation mechanism for ICE is the magnetoacoustic cyclotron instability(MCI); in the case of JET and TFTR, the MCI is driven by a set of centrallyborn fusion products, lying just inside the trapped-passing boundary invelocity space, whose drift orbits make large radial excursions to the outermid-plane edge. Diagnostic exploitation of ICE in future experiments thereforerests in part on deep understanding of the MCI, and recent advances incomputational plasma physics have led to substantial recent progress, reviewedhere.
