Transport/hydrodynamic simulation of intense ion beam diagnostics (abstract)

Sandia is working towards igniting an ICF target using MJ‐level ion beams focused to intensities of up to 100 TW cm2. The diagnostics used to confirm the achieved focal intensities and study the beam‐target interactions are sensitive to variations in both ion energy and angle of incidence. Therefore, to properly simulate time‐integrated and time‐dependent diagnostics, a coupled transport/diagnostic model is required. Further, intense ion beams cause hydrodynamic response of the target material. We have been developing both a transport/diagnostic code, PICDIAG, and a coupled 1‐D rad/hydro/CRE capability to study these effects. We will describe the models used as well as the results of recent simulations of intense beam‐target experiments on PBFA II. This will include simulations of diagnostics utilizing Rutherford scattering, inner‐shell x‐ray generation, and nuclear activation, as well as shadowboxes. Comparison with experimental data will be emphasized. This work was supported by the U. S. Department of ...
