SUPPRESSION OF INTERNAL PLASMA OSCILLATIONS BY TRAPPED HIGH ENERGY NUCLEI
The suppression of macroscopic oscillations (so- called sawteeth) of the central region of a magnetically confined plasma column is related to the effect of magnetically trapped energetic nuclei produced by the injection of rf waves or neutral beams. We evaluate the threshold for, and describe the process involved in, the transition of m"0" = 1 modes, which trigger the crash phase of sawtooth oscillations, to a regime that is shown to be stable.
