The Pinch Effect Revisited
The article presents a broad survey of research associated with the pinch effect, i.e., the self-constriction of the column of a deformable conductor carrying an electric current. Research conducted from 1954 to 1963 centered on developing a scheme which would utilize axial magnetic fields, RF fields, and conducting walls to stabilize the pinched plasma column while part of the fuel reacts; these schemes are described. Work during the 1964-1974 period dealt with developing the plasma focus and self-consistent field patterns for diamagnetic and paramagnetic vortex filaments. Various theories concerning the mechanism and mode for deuteron energizing and directing in the pinch effect and plasma focus are outlined.
