The design and interpretation of inertial confinement fusion and high energy density ex- periments relies 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 devel- opment 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].

We report on new software tools and their first applications: X-ray radiogra- phy for shock compression of matter [2], neutron spectrometry [3] (used to interpret exploding pusher experiments [4]), and fast charged particle spectrometry for stopping power measurements [5]
