“…Pulsed-power driven liner implosions can be used to produce extreme pressure states in condensed matter that are relevant to the study of planetary interiors, astrophysics, and inertial confinement fusion [1]. The Z accelerator [2,3] delivers a current pulse to a cylindrical liner (tubular shell) that rises to a peak of 20-26 MA in ~100 ns (depending on load inductance).…”

“…This paper will summarize some of the results of the first Atlas experimental series at the Nevada Test Site. The 2006 series included two implosion dynamics experiments, two experiments exploring damage and material failure to complement an on-going series of pulsed-power-driven Damage experiments conducted jointly with VNIIEF in Sarov, a new advanced hydrodynamics series aimed at studying the behavior of damaged material ejected into a gas from a shocked surface; and a new series exploring friction at sliding interfaces under conditions of high normal pressure and high relative velocities 1 .…”

Pulsed Power Hydrodynamics (PPH) is a new application of low-impedance, pulsed power technology to the study of complex hydrodynamics, instabilities, turbulence, and material properties in a highly precise, controllable environment at the extremes of pressure and material velocity. The Atlas facility, designed and built by Los Alamos, is the world's first, and only, laboratory pulsed power system designed specifically to explore this relatively new family of pulsed power applications. Constructed in the year 2000 and commissioned in August 2001, Atlas is a 24-MJ high-performance capacitor bank delivering currents up to 30-Megamperes with a rise time of 5 to 6-µsec. The high-precision, cylindrically imploding liner is the tool most frequently used to convert electromagnetic energy into the hydrodynamic (particle kinetic) energy needed to drive strong shocks, quasi-isentropic compression, or large volume, adiabatic compression for the experiments. At typical parameters, a 30-gr, 1-mm-thick liner with an initial radius of 5-cm, and an intermediate current of 20-MA can be accelerated to 7.5-km/sec producing megabar shocks in medium density targets. Velocities up to 20km/sec and pressures >20-Mbar in high density targets are possible.

This paper reports on the development of a magnetically driven high-velocity implosion experiment conducted on the CQ-3 facility, a compact pulsed power generator with a load current of 2.1 MA. The current generates a high Lorentz force between inner and outer liners made from 2024 aluminum. Equally positioned photonic Doppler velocimetry probes record the liner velocities. In experiment CQ3-Shot137, the inner liner imploded with a radial converging velocity of 6.57 km/s while the outer liner expanded at a much lower velocity. One-dimensional magneto-hydrodynamics simulation with proper material models provided curves of velocity versus time that agree well with the experimental measurements. Simulation then shows that the inner liner underwent a shock-less compression to approximately 19 GPa and reached an off-Hugoniot high-pressure state. According to the scaling law that the maximum loading pressure is proportional to the square of the load current amplitude, the results demonstrate that such a compact capacitor bank as CQ-3 has the potential to generate pressure as high as 100 GPa within the inner liner in such an implosion experiment. It is emphasized that the technique described in this paper can be easily replicated at low cost.
