1. A method for generating and containing plasma in a reversed field pinch with a magnetic well, said method comprising:

  • generating toroidal plasma in a toroidal chamber having a major toroidal axis and a minor toroidal axis and a small aspect ratio;

    passing current through said plasma in the direction in which said minor toroidal axis extends to form a strongly reversed magnetic field pinch configuration therein which generates a set of nested closed magnetic flux surfaces defining an elliptic magnetic axis within said plasma extending in the direction of current flow and produces a safety factor q which changes sign within said plasma at the flux surface where the component of the magnetic field in the direction in which said minor toroidal axis extends changes sign; and

    generating at least one hyperbolic magnetic axis outside substantially all of said plasma and between said elliptic magnetic axis and said major toroidal axis to form an average magnetic well encompassing substantially all of said plasma.
