Three-dimensional magnetic field enhancement in a liner implosion system

The magnetic field enhancement is calculated for a magnetically imploded liner system that has flux excluding radial vanes. For the thinnest vane tested the field is found to concentrate at the vanes to a maximum value of almost three times its ambient value with a corresponding temperature increase well above the melting point. These values are calculated using the three-dimensional magnetohydrodgnamic code, MACH3. Calculations are performed for three vane thicknesses, and the vane movement is estimated. A bound is established on the design specification of the vanes based the disruption of current delivery to the liner due to the movement of the vanes.<
