Confinement of plasma in a purely toroidal magnetic trap with a self-consistent electric field
Abstract
A possible mechanism for the formation of an equilibrium plasma configuration of a currentless toroidal pinch enclosed in a conducting chamber in a toroidal magnetic field is described. The rotation of the plasma with respect to the azimuth of the minor section in crossed fields acts as the rotational transformation. Electric fields of sufficient intensity are formed automatically as a result of charge separation caused by toroidal drift or as a result of predominant losses of particles of the same sign. The macroscopic force balancing the uncompensated part of the gas kinetic pressure along the major radius is the force of interaction of the excess plasma charge with the charge of the image on the inner wall of the conducting chamber. It is shown as an estimate that this does not require very high fields if the polarizability of a dense plasma is taken into account.
