Laser-based, Multi-species, Radiography for Small and Medium Scale Dynamic Experiments

Time resolved (flash) radiography is an established technique for imaging dynamic experiments over a wide range of temporal and spatial scales, materials, and densities. Radiographic techniques most often employ one probing species (x-rays, protons, electrons or even neutrons), and most radiographic systems have been highly optimized for each species, and sometimes specialized to specific experiments. Since the interaction physics (atomic, colomb, elastic) of each probing species with the target materials differs, the information mapped from the target to the imaging detector will be different among probe species. Near simultaneous, point-projection probing, with multiple species, potentially coupled with AI analysis techniques, may produce a more complete description of the dynamic experiment than can be gained from mapping with any single species.
