Abstract Text:
Sheared azimuthal flow has the potential to stabilize z-pinch implosions [1]. Recent numerical results in particular, indicate that sheared azimuthal flow reduces the growth rate of the m = 0 sausage and m = 1 kink instabilities [2]. Here we propose an experiment to apply these results to an imploding wire array to reduce the Rayleigh-Taylor, sausage, and kink instabilities. Sheared azimuthal flow is here generated by a magnetic cusp produced by opposing solenoids, placing the wire array in the center of the cusp. The axisymmetric radial magnetic field of the cusp will cause the imploding plasma to rotate by the j cross B force. An efficient load for this experiment can be created by placing the opposing solenoids in series with the cylindrical wire array [3].
