ResumoThe general properties of electron cyclotron radiation emitted by the current-carrying superthermal tail in tokamak plasmas are investigated. Two situations are considered, namely, the case of an extended tail as it occurs in present-day experiments and that in which the velocity range of the tail is much less than its mean speed. For the former case, we show that most of the emitted radiation obeys Kirchhoff’s law. In the latter case, which is suited for reactor-like parameters, a simple relation is obtained between the tail momentum distribution and the radiation temperature.
