1. An accelerator with a closed electron drift, comprising:

  • an annular magnetic circuit having a first magnetic pole tip and a second magnetic pole tip, said first magnetic tip and said second magnetic tip separated by a gap, said gap defining a discharge chamber;

    an external ring cathode and an internal ring cathode, said external ring cathode positioned adjacent to said first magnetic tip in said gap and said internal ring cathode positioned adjacent to said second magnetic tip in said gap;

    an anode positioned between said ring cathodes in said gap and comprisinga first annular section having a first axis;

    a second annular section adjacent to said first annular section along said first axis;

    a tube mounted to said first annular section along said axis to provide gas to said discharge chamber, said tube permitting said anode to be positioned along said axis a distance L, wherein said distance L satisfies the equation
    
    
    space="preserve" listing-type="equation">-L.sub.1 <

    L<

    L.sub.2, whereL1 is a displacement with respect to an outermost edge of said external cathode ring; and

    represented by the equation;

    ##EQU5## where;

    e is electron charge;

    m is electron mass;

    VP is applied voltage;

    ω

    e is cyclotron electron frequency;

    Ve is electron scattering frequency;

    Vi is ionizing collision frequency; and

    L2 is the distance of said gap;

    an electron source in electrical communication with said magnetic circuit;

    a power source in electrical communication with said magnetic circuit; and

    a magnetomotive force source in communication with said magnetic circuit.
