Executive Summary

We are developing a short-pulse, laser-driven particle beam capability that will expand the exploration of high-energy-density physics of ultra-extreme states of matter. By enabling applications such as proton and neutron radiography, multi-view tomography, and unique nuclear reactions, this research supports stockpile stewardship.
