ABSTRACT
A general class of methods is suggested for producing controlled magnetic fields up to the order of 100 MG. The methods involve radially imploding plasmas in which longitudinal magnetic fields have been entrained. Specific methods of implosion suggested are (a) gas-puff Z pinch and (b) ablative implosion of a liner by a laser. Applications include reducing fusion ignition thresholds, producing beams of gamma radiation, accelerating particles, and producing high-energy densities under controlled conditions.

    Several discrete symmetry parameters characterizing axisymmetric toroidal plasmas have been introduced. For a device without up-down symmetry such parameters are S[sub 1], related to the handedness of the toroidal current, S[sub 2], related to the direction of the toroidal velocity, and S[sub...

    The study of the wire array implosion on installation Angara-5-1 is devoted. Magnetic probes and the x-ray backlighting technique were used to investigate a current and mass distribution during the implosion.

    An effect of the global magnetic field on the ablation rate of wire cores in wire array Z-pinch experiments was studied using wire arrays with fixed wire number but different array diameter. The data suggest that the ablation rate is higher for the arrays with smaller diameter, when the global...
