Plasma gun supersonic vortex magnetohydrodynamic dynamo for magnetized target fusion

Abstract

Supersonic plasma jets injected with a large azimuthal velocity component into a magnetic cusp field entrap the radial field component in between the coalescing jets, with the cushioning effect of the magnetic field diminishing the formation of shocks which otherwise would occur by the collision of the jets. With the bending of the radial magnetic lines of force into an azimuthal direction by the vortex flow of the coalescing jets, a magnetohydrodynamic dynamo with an axial current is established. With the radial velocity component of the jets compressing the magnetic field and the plasma formed by the coalescing jets, a closed field line configuration is established. If dense denterium–tritium (DT) gas is injected into the vortex core, the axial current passes through the DT resulting in a dense pinch discharge stabilized by the rapidly rotating vortex flow.
