(Science: radiobiology) The plasma focus is another device which depends on the pinch effect. 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. Plasma focus is sort of a point version of the Zpinch.
