Anode Implosion Radius Effects on Dense Plasma Focus Performance

POSTER

Abstract

Dense plasma focus (DPF) Z-pinches are compact pulsed power driven devices consisting of two coaxial electrodes, separated by an insulator, and filled with a low-density gas. MJOLNIR is a dense plasma focus (DPF) located at LLNL being developed to produce a neutron source for flash neutron radiography and has produced greater than 10^12 neutrons when driven with up to 3.8 MA. Producing a neutron source for radiography requires both a bright neutron pulse as well as the neutrons emanating from a small volume. Simulation and experimental results will be presented on neutron yield, and stagnation characteristics for anodes with a variety of implosion radii, the radius at which the implosion starts for both the 100 kA and 3 MA DPFs at LLNL.
