A TRIPLE WAVE RESONANCE MODEL FOR THE EMISSION FROM TOKAMAKS OF NARROW BAND BURSTS OF RADIATION AT THE PLASMA FREQUENCY
When the distribution of electron velocities parallel to the magnetic field has a tail with a bump, a linear triple wave resonance instability can cause the growth of electromagnetic waves at w-p. The bandwidth of the radiation depends on the ratio of the number of electrons in the tail to the total number of electrons; the smaller this ratio, the narrower the bandwidth. The instability occurs only when the mean tail velocity takes a specific value. The radiation thus gives an indication of tail structure.
