In the last five years, a new application of high-performance pulsed power
techniques within the Stockpile Stewardship Program has joined the traditio
nal family of radiation source applications. This new application uses low-
impedance, high-current drivers to produce high-energy density environments
in materials for the study of material properties, instabilities, and hydr
odynamics in complex geometries. The principle tool for producing high-ener
gy density environments is the high-precision, magnetically imploded, near-
solid density liner. The most attractive pulsed power system for driving su
ch experiments is an ultrahigh current, low-impedance, microsecond rise-tim
e source that is economical both to build and to operate.
In this paper we will review basic scaling arguments that set the scope of
high-energy density environments made available by pulsed power-driven line
rs. We provide a summary of some investigations into the physics limiting t
he performance of near-solid metal liners under magnetic drive. We mill pre
sent a fell examples of hydrodynamic experiments enabled by liners drive an
d note some demonstration experiments already performed with inter im syste
ms. Finally, me will overview the pulsed power techniques under development
at Los Alamos for high-energy density experiments.
