Executive Summary
We are studying the potential of lasers to produce megaelectronvolt sources for taking radiographs of large, dense objects, such as those produced during implosions driven by high explosives. Such a laser-driven facility could provide simultaneous neutron and x-ray radiography, opening up new diagnostic possibilities relevant to national stockpile stewardship efforts while reducing the number of stockpile stewardship experiments required.
