ATLAS Pulsed-Power Generator
 Since
the cessation of underground nuclear testing in 1992, above-ground
laboratory and underground subcritical experiments have provided the
principal source of new experimental data to benchmark and improve
predictive models for nuclear weapons performance and reliability.
Developing accurate, reliable models that provide the confidence needed
to recertify stockpile weapons without nuclear testing is the main goal
of the National Nuclear Security Administration's Stockpile Stewardship
Program. The Atlas pulsed power machine is one of many alternatives to
underground nuclear testing.
Pulsed power can concentrate high total energies on larger
(centimeter-scale) experimental targets for relatively long periods of
times compared to other Stockpile Stewardship experiments. The data from
pulsed power experiments allows the Stockpile Stewardship Program to
develop better physics models of material properties and implosion
hydrodynamics and radiation flow.
