Title: Linear Theory of Collisionless Drift Instability
Abstract:
An integral eigenmode equation will be given to determine the stability of drift wave in tokamaks. Numerical solutions in the parameter space show a wide variety of the behavior of eigenvalues and eigenfunctions. It indicates that the ion dynamics are particularly important.
Additionally, we may discuss a integral model in slab limit, which reveals the instability of electron drift wave in the presence of magnetic shear.
