AB - We report on the implosion dynamics of single nickel and copper wire arrays on the MAGPIE generator with a 1.4 MA, 240 ns current pulse. Plasma formed from individual wires has a corecorona structure. In the nickel arrays, a core size of 75 μm is measured by x-ray radiography. The formation of precursor on axis takes place at about 150 ns. Initially the precursor plasma is stable but shows an m=1 instability later in time. The implosion of the array occurs later than that predicted by a 0-D model, indicating that a fraction of the current flows through the precursor plasma. Like aluminum and tungsten, the m=1 instability in the precursor plasma is not observed in the copper arrays, and the implosion time is in accordance with a 0-D model. This implies that the resistivity of the wires play an important role in the dynamics of the wire arrays. Detailed results will be presented.
