Abstract

Process for removing or displacing unwanted plasma comprises creating in the plasma electric and magnetic fields perpendicular to each other, the direction of plasma displacement being determined by the vector prod. of the two fields. Specifically, the process is for removing plasma from the vicinity of a wave emitter or for controlling the field strength of the ions at the point in a plasma where electromagnetic waves are being input; the magnetic and electric fields are applied at the output of the wave emitter. The emitter esp. consists of a wave guide inserted into a toroidal plasma-containing vessel, and an electric field is applied perpendicular to the magnetic field already present. Method is esp. for use in 'Tokamak' type controlled fusion reactions where a wave guide is used for the final stage of heating the plasma to the required temp.
