Global approach to the spectral problem of microinstabilities in tokamak using a gyrokinetic model
A root finding algorithm for identifying the eigenfrequencies, based on a higher order Nyquist method, enables straightforward implementation on a parallel computer. Illustrative results of ion temperature gradient (ITG) -related instabilities are presented. These include scaling studies of the radial width, toroidicity and magnetic shear scans, as well as the effects of non-adiabatic trapped electron dynamics.
