An Introduction to the Neoclassical Transport Theory (Lecture note)

Nov. 1995

Key words:

neoclassical transport, parallel viscosity force, frictional force, bootstrap current, banana diffusion, tokamak, helical system

Abstract:

An introduction is given to the theory for neoclassical transports mainly in an axisymmetric tokamak. The bootstrap current, which has been experimentally observed in tokamaks and helical systems, is generated by balancing the parallel viscosity force and frictional force. In axisymmetric tokamaks, the banana diffusion is also caused by the parallel viscosity force. The bootstrap current in helical systems is briefly mentioned.
