Abstract
The tokamak shaping effects on the toroidal branch of the ion-temperat ure-gradient-driven mode in the long wavelength limit (k(chi)2rho(i)2 much less than epsilon(T)1/2) are studied. A model equilibrium with no ncircular cross section is employed, where elongation, Shafranov shift , and triangularity are all taken into account. It is shown that each Fourier term in the expansion of the equilibrium magnetic field is ass ociated with a new branch of the dispersion relation.
