Experimental results of pulsed-power-driven radial and rotating outflows to study accretion-driven stellar jets

In this poster, we present recent data from several campaigns executed on Cornell's COBRA driver with the goal of studying the influence of magnetic field geometry and rotational velocity on the properties of the resultant bipolar outflow. For each campaign we focused on generating either purely radial-to-axial outflows or rotating "accretion-style" bipolar outflows. We used multiple designs of a 3D printed wire array holder to control the injection direction of the ablation stream from the wires, as well as the ratio of axial to azimuthal magnetic field. The properties of the outflows were characterized by temperature, velocity and density using interferometry, gated optical and ultraviolet imaging, and Thomson scattering diagnostics. We discuss the implications of these measurements and plans for future experimental campaigns.
