Self-Consistent Simulation of Dynamic Radiography Physics Applications
Abstract
A self-consistent simulation capability described in the preceding presentation has been used to generate synthetic radiographs of a dynamically evolving object. This capability consists of a suite of simulation codes, which individually model hydrodynamic, electromagnetic, and charged particle and photon transport phenomena, and are chained together in a logical manner to model an entire multiple-pulse radiographic event. The resulting radiographs are numerically reconstructed to determine material edges and density distributions. The results, obtained at different times, are compared with hydrodynamic simulations of the object. Hydrodynamic simulations were carried out to predict the evolution of the converter target after each deposition of energy by the successive electron pulses. We have incorporated hydrodynamic, electromagnetic, photon and electron transport, detector response, and scatter background, in the simulation sequence. Our simulations have demonstrated the utility of forward reconstruction method through real dynamic objects. Details of the calculations will be presented.
