The theory takes account of all particle motion associated with toroidal geometry; specifically, ''∇ B'' and curvature drifts, | The theory takes account of all particle motion associated with toroidal geometry; specifically, ''∇ B'' and curvature drifts, and passing and trapped particles (banana orbits). | ||
The theory is valid for all collisionality regimes, and includes effects due to resistivity and viscosity. An important prediction of the theory is the [[Bootstrap current|bootstrap current]]. | The theory is valid for all collisionality regimes, and includes effects due to resistivity and viscosity.
