Possible applications include both fusion and plasma propulsion, as well as other plasma research. In essence the plasma focus is generated by discharge of a current across the ends of two coaxial insulated conducting pipes. The Plasma Focus caused a huge stir when they generated copious neutrons, until it was discovered that the source of the neutrons was knockoffs from deuterium due to pinch accelerated electrons or ions. Fusion reaction which occurs from the collision of two thermal plasma ions. A disturbance of a plasma away from equilibrium, involving oscillations of the plasma's constituent particles and of an electromagnetic field.
Plasma waves can propagate from one point in the plasma to another without net motion of the plasma.
In this regime, the transport coefficients are independent of the collision frequency. Pu is used in nuclear weapons and as a fission reactor fuel. In toroidal geometries, the direction along the circumference of a slice through one side of the torus. In toroidal devices, the magnetic field that encircles the plasma axis. These include ohmic heating, shaping, vertical, equilibrium, and divertor windings.
