Abstract

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].
