Higher Energy Proton Radiography as an HED Diagnostic

 

Proton radiography at 800-MeV has established itself as a powerful, fast diagnostic of high explosives and high energy density states. Work is now under way to explore 3-GeV proton radiography at the GSI SIS-18 beamline in Darmstadt, Germany as a probe for HE-driven materials studies. Similar systems are under study for the future of LANSCE, and radiographic predictions from Monte Carlo forward models will be shown here. The increased proton energy, and decreased beam emittance, allow for thicker amounts of material to be probed at higher spatial resolutions. Additionally, the increased flux provided by an upgraded accelerator allows for thinner, faster systems to be probed. The ultimate goal will be to implement a radiographic system with a dramatically increased dynamic range, temporal profile, and spatial resolution.
