Differentially rotating free-boundary plasma experiments at the MAGPIE facility

We will present results from pulsed-power driven differentially rotating plasma experiment, which uses x-rays generated by wire array z-pinch implosions to create converging plasma flows with non-zero angular momentum. Measurements of the plasma parameters with TS, interferometry and fast gated cameras show formation of a hollow and stable rotating cylinder with quasi-Keplerian velocity profile, sustained for more than one full rotation by the ram pressure of the converging flows. The large Reynolds (Re~10⁵) and magnetic Reynolds (Rem~20) numbers characterising this rotating plasma, and the possibility to controllably add an axial or cusp B-field, allows a direct test of the effects of the magnetic fields on the structure and stability of the plasma.
