  1. Measurements of Magnetic Compression and Melt of Electrically Thick Metals Driven by Lineal Current Densities Characteristic of Pulsed-Power-Driven Fusion Devices

    Photonic Doppler velocimetry (PDV) has enabled high-resolution measurements of surface motion on z-pinches, revealing previously unobserved phenomena such as pre-melt radial magnetic compression followed by changes in acceleration corresponding to the solid-liquid phase transition of the surface of …

  3. Verification and Validation of Magnetohydrodynamics Simulations of Electrically Exploded Conductors

    … significant for plasma formation. Experimental velocimetry measurements were used to validate the location of the vaporization curve in existing EOS models and differentiate between the vapor dome treatments. Dielectric coatings applied to the metal surface restricted the conductor's expansion …
