Abstract

Externally produced neutral particle beams and electromagnetic (EM) fields can penetrate well inside a magnetized, fully ionized plasma across the confining magnetic field lines and produce bulk plasma heating as well as current drive. The neutral particles must be of sufficiently high speed so that they do not ionize until well inside the plasma.

Conditions for EM energy propagation across the confining magnetic field lines and absorption within the confined plasma exist over a wide range of situations compatible with a thermonuclear environment. However, they are less straightforward than in the previous case, primarily because of the subtle role played by Coulomb collisions in the long mean free path limit, concurrently with the EM wave action.

In these lectures some attention will be devoted to describing and clarifying the physical mechanisms underlying radiofrequency heating and current drive schemes.
