Thonemann, P C

A pinch device is described for heating gases to nuclear interaction temperatures. It consists of a toroidal vessel, a primary winding with conductors around and parallel to the torus circular axis, and a means for exciting the winding to induce a ring discharge in the torus gas, preferably an r- f source. Temperatures of the order of 10/sup 7/ tained K can be obtained without excessive power dissipation at the tube wall. External stray r- f magnetic fields are eliminated by a toroidal Cu shield with insulating joints enclosing the gas space. When the discharge current reaches several hundred amp, the discharge is restricted and the pressure can be further reduced, e.g., to 10/ sup -5/ mm Hg, thus reducing ion pair generation and wall power dissipation; therefore, the ions tend to come into temperature equilibrium with the electrons.
