粒子閉じ込めと衝突拡散

抄録

Single particle confinement or particle orbit and collisional diffusion are reviewed for general toroidal systems. The single particle confinement or particle orbit is described using the guiding center approximation. Effects of the radial electric field are also considered. Neoclassical features are explained intuitively by using the characteristics of the single particle orbits and effective Coulomb collision frequencies. As an advanced treatment, the neoclassical theory is systematically given on the basis of the moment approach.
