Experimental Demonstration of Dynamical Similarity of the Preseeded Magneto-Rayleigh-Taylor Instability in Scaled Z-Pinch Implosions

D. E. Ruiz, David Yager-Elorriaga, Jeffrey Fein, J. Carpenter et autres

With the achievement of thermonuclear ignition, there is interest to increase the performance of inertial-confinement-fusion (ICF) systems to reach high fusion yields and high-energy gain for energy-production purposes. One approach to achieve this is magnetic-direct-drive (MDD) ICF, where magnetic fields are used …

Rotation of electrothermal-instability-driven overheating structure due to helically oriented surface magnetic field on a high-current-density aluminum rod

T. J. Awe, Edmund Yu, Gabriel Shipley, Kevin Yates et autres

Experiments on the 1-MA, 100-ns-rise-time Mykonos Facility demonstrate rotation of electrothermal instability (ETI)-driven overheating structure on 1.00-mm-diameter, 10-nm-surface roughness, 99.999%-pure aluminum rods, which are pulsed with helically polarized surface magnetic field. Rods are machined to include pairs of 10-micron-scale quasi-hemispherical voids or …
