Book Description
It is pointed out that despite an abundance of investigations of hydromagnetic stability of toroidal plasma configurations, the problem still remains unsolved. In particular, the meaning of the general geometric Mercier criterion which plays an important role in modern calculations of stability of concrete systems remains unclear. A general theory of local instability is developed in the present paper from which it followed that the Mercier criterion is a necessary and sufficient condition for plasma stability with respect to a particular class of local perturbations, such as those for which the radial wavelength is small with respect to the wavelength along the small azimuth.
