Experimental studies of radiatively cooled supersonic plasma jets produced in wire array z-pinches*

We will present results of recent experiments with radiatively cooled supersonic plasma jets performed on the pulsed power MAGPIE facility (1.5MA, 250ns) at Imperial College. The jets are produced by the plasma ablated from the wires arranged in conical or radial configurations. Convergence of the flow on the axis of symmetry of the system produces plasma jets with dimensionless parameters (Mach number $\sim $20, cooling parameter $\sim $1) similar to those in proto-stellar jets, and the flow has high Reynolds number ($>$10$^5$). We will present measurements of the jet parameters obtained with laser and XUV diagnostics providing high spatial resolution, and will discuss how this set-up can be scaled to 20MA Z facility.
