Stellarator Kinetic Theory

A very important field of stellarator theory is based on the kinetic equations. This paper reviews the kinetic equations and the reduction of the phase-space dimension by averaging of the fastest time scales. The difference of stellarators to axisymmetric tokamaks is discussed, and the main aspects for stellarator confinement optimization in the neoclassical theory are analyzed. Stellerator-specific applications of the kinetic theory are given in examples.
