1. A method of producing a field-reversed mirror plasma, comprising the steps of:

  • producing a minimum B magnetic field of multi-Tesla strength in an evacuated plasma confinement apparatus by means of a magnetic mirror;

    generating a plasma ring by means of a coaxial plasma gun, said coaxial plasma gun possessing a solenoidal conductor configuration so as to produce a poloidal magnetic field, the inner component of said poloidal field being in a direction opposite to that of the magnetic field of the mirror so as to form a magnetic field-reversed configuration around the gun;

    accelerating the plasma ring by means of said coaxial plasma gun so that the plasma ring drifts out of and away from the coaxial plasma gun in a direction parallel to the coaxial plasma gun'"'"'s longitudinal axis and toward said magnetic mirror, thus forming a field-reversed plasma ring upon reconnection of the magnetic field lines between said plasma ring and said coaxial plasma gun; and

    confining the field-reversed plasma ring in the minimum B magnetic well of the magnetic mirror thereby producing a field-reversed mirror plasma.
