Query: The m/n=1/1 Instabilities in An EAST NBI Discharge   An analysis of precession fishbone, diamagnetic fishbone and internal kink
mode in Tokamak plasmas are presented via solving the fishbone dispersion
relation. Applying the dispersion relation to EAST discharge experiment,
excitation of precession fishbone due to Neutral Beam Injection is successfully
explained. Real frequency and growth rate of diamagnetic fishbone and internal
kink mode are calculated.
