摘要
A magnetic well reversed field plasma pinch method and apparatus produces hot magnetically confined pinch plasma in a toroidal chamber having a major toroidal axis and a minor toroidal axis and a small aspect ratio. A reversed magnetic field pinch current channel within the plasma and at least one hyperbolic magnetic axis outside substantially all of the plasma form thereby a region of average magnetic well in a region of nested closed magnetic surfaces surrounding the plasma current channel when the magnetic field component in the direction of the hyperbolic magnetic axis is also made to be substantially less than zero in the vicinity of the hyperbolic magnetic axis. The magnetic well reversed field pinch is operated so that reversal of the safety factor q and of the toroidal magnetic field takes place within the plasma, and the plasma so produced closely approximates known theoretical stability conditions. The well-producing plasma cross section shape is produced effectively by an exterior shaping shell assembly. The plasma is formed inside a vacuum chamber and an electrically conducting shaping shell assembly, whose noncircular poloidal cross section imparts the desired shape to the plasma. The shape of the plasma may be maintained and/or adjusted by means of electrical currents driven through appropriately distributed external conductors.
