  A suite of synthetic nuclear diagnostics has been developed to post-process
radiation hydrodynamics simulations performed with the code Chimera. These
provide experimental observables based on simulated capsule properties and are
used to assess alternative experimental and data analysis techniques. These
diagnostics include neutron spectroscopy, primary and scattered neutron
imaging, neutron activation, $\gamma$-ray time histories and carbon
$\gamma$-ray imaging. Novel features of the neutron spectrum have been analysed
to infer plasma parameters. The nT and nD backscatter edges have been shown to
provide a shell velocity measurement. Areal density asymmetries created by low
mode perturbations have been inferred from the slope of the downscatter
spectrum down to 10 MeV. Neutron activation diagnostics showed significant
aliasing of high mode areal density asymmetries when observing a capsule
implosion with 3D multimode perturbations applied. Carbon $\gamma$-ray imaging
could be used to image the ablator at high convergence ratio. Time histories of
both the fusion and carbon $\gamma$ signals showed a greater time difference
between peak intensities for the perturbed case when compared to a symmetric
simulation.
