We present results from GORGON, a three dimensional, parallel, radiative, resistive MHD code which we use to study the evolution of various wire array configurations. We describe the implosion of cylindrical wire arrays and the interaction of nested wire arrays on the MAGPIE generator of Imperial College. In addition to cylindrical arrays we describe results from the modeling of novel array configurations such as radial, conical and spherical wire arrays, which are of interest in laboratory astrophysics, and the understanding of basic array physics. For spherical array implosions we demonstrate a precursor flow convergence that is not entirely spherical. We show that jet formation on axis, and compression from precursor streams generates a roughly cylindrical precursor, which at late times becomes unstable. Final implosion is dominated by two magnetic cavities that expand axially to collide at the array center.This research supported by the NNSA under Department of Energy cooperative agreement DE-F03-02NA00057.
