Dense z-pinch plasmas initiated from a single 25--100 [mu]m diam aluminum wire using a 100--350 kA, 100 ns current pulse have been studied with [le]1 ns time resolution. Rapid unstable expansion of a coronal plasma formed around the wire was observed with a subnanosecond pulsed nitrogen laser, while a dense core, which expanded more slowly and stably, was observed with 1--2 ns x-ray backlighting pulses. The core contained most of the initial wire mass, but there appeared to be little or no current flowing in it.
