In this paper, collimated plasma jets form from Joule heating and ablation of a radial foil (Al 15-$\mu \text{m}$ -thin disk) using a pulsed power generator (Cornell Beam Research Accelerator) with 1-MA peak current and 100-ns rise time. Plasma dynamics of the jet are diagnosed with and without an applied uniform external magnetic field ($\sim 1$ -T axial $B_{z}$ produced from a pulsed Helmholtz...
We present investigations of gas puff Z-pinch implosions with an applied external Bz field. The experiments are conducted on the 1-MA, 200-ns COBRA generator. Stabilized 200-ns, high current z-pinch implosions have been demonstrated by using double or triple-gas puffs. In the experiments, a triple-nozzle is used to produce z-pinch loads with concentric outer, inner and center gas puff columns. Implosion...
Radial foil implosions on pulsed-power generators [1] can produce strongly collimated plasma jets. The typical ratio of the jet length to its radius is at least 20. These jets have large Reynolds and magnetic Reynolds numbers. Due to favorable scaling [2], they can be considered as a reasonable embodiment of collimated astrophysical plasma jets generated by protostars, planetary nebula or galactic...
Tests of the magnetized liner inertial fusion (MagLIF) concept will make use of the 27 MA Z-machine at Sandia National Laboratories, Albuquerque, to implode a cylindrical metal liner to compress and heat a preheated plasma contained within it [1]. While most pulsed power machines produce much lower currents than the Z-machine, there are questions that can still be answered on smaller scale setups...
