Kinetic theory of particles near resonances is a current topic discussion in plasma physics and astrophysics. We extend this to the kinetic interaction between alpha (energetic predicted exist large quantities next-generation fusion experiments) neoclassical tearing mode (NTM), resistively-driven perturbation that sometimes exists tokamak. develop quasilinear treatment alphas an NTM, showing why NTM can be source significant passing particle transport tokamaks. The limitations on constrain our theory's applicability small amplitude NTMs, highlighting importance nonlinear studies.
