Title: HEL-1: A DEMG Based Demonstration of Solid Liner Implosions at 100 MA

Abstract

In August 1997, the Los Alamos National Laboratory (LANL) and the All-Russian Scientific Research Institute of Experimental Physics (VNIIEF) conducted a joint experiment in Sarov, Russia to demonstrate the feasibility of applying explosive pulsed power technology to implode large scale, high velocity cylindrical liners. Kilogram mass metal liners imploding at velocities of 5-25 km/sec are useful scientific tools for producing high energy density environments, ultra high pressure shocks, and for the rapid compression of plasmas. To explore the issues associated with the design, operation and diagnosis of such implosions, VNIIEF and LANL designed and executed an practical demonstration in which a liner of approximately 1 kilogram mass was accelerated to 510 km/sec while undergoing a convergence of about 4:1. The scientific objectives of the experiment were threefold. First to explore the limits of very large, explosive, pulse power system delivering about 100 MA as drivers for accelerating solid density imploding liners to kinetic energies of 25 MJ or greater. Second to evaluate the behavior of single material (aluminum) liners imploding at 510 km/sec velocities by comparing experimental data with 1-D and 2-D numerical simulations. Third, to evaluate the condition of the selected liner at radial convergence of 4 and amore » final radius of 6 cm. A liner of such parameters could be used as a driver for equation of state measurements at megabar pressures or as a driver for a future experiment in which a magnetized fusion plasma would be compressed to approach ignition conditions.« less
