Vs. Belikov et al., COHERENT CYCLOTRON THERMONUCLEAR INSTABILITY DRIVEN BY CIRCULATING PARTICLES IN TOKAMAKS, Nuclear fusion, 36(11), 1996, pp. 1583-1585
It is shown that circulating fast ions can lead to a slow coherent cyc
lotron magnetoacoustic instability in tokamaks, provided their velocit
y distribution is strongly anisotropic.
