Synthetic diagnostics for interpretation of ICF experiments using hydrodynamic simulations
The design and interpretation of inertial confinement fusion and high energy density experiments
rely heavily on multi-dimensional radiation-hydrodynamic simulations. Code main
output typically consists of sequences of maps of fluid and thermodynamic variables, which are
not easily compared with experimental observables. More direct comparison requires the development
of simulated, or synthetic, diagnostics, using the detailed plasma information available
in the fluid simulations. This has motivated the development of a set of simulated diagnostics
coupled, either on-line or off-line, to our 2D Lagrangian code DUED [1, 2].
We report on two new software tools: x-ray radiography [3] for shock compression of matter
and fast charged particle spectrometry for stopping power measurements. In addition, we are
developing synthetic streaked optical pyrometry and we are improving neutron spectrometry
software, already partly described in Ref. [4], and recently used to interpret exploding pusher
experiments [5].
