“…Studies on warm, gas-filled exploding pusher target implosions reported significant anisotropy attributed to target alignment [57], target mounting [58], capsule defects [59], and non-uniform illumination [60]. For example, the effect of dropping two of the 48 NIF laser quads leads to substantial asymmetry in density and implosion velocity without precise redistribution of the remaining laser energy.…”

“…An FNADs system based on a lanthanum bromide scintillators and compact gamma spectrometers installed in the target bay is being developed to provide immediate postshot readout of yield [58]. This system will have additional capability to measure multiple DT neutron reactions and other neutron source terms, such as TT and DD fusion reaction neutrons [59,60]. In ICF experiments with D 2 , DT or THD targets the nToF diagnostics measure the neutron yield as a function of neutron energy by recording detector signal strength over time using the known flight path length to deduce the neutron energy.…”

“…Such components are tested to a fluence greater than that a component would experience during operation. The testing consisted of component irradiation using a 60 Co gamma source and accelerator-based irradiation using a 14 MeV neutron source. The Edwards Accelerator Facility located at the Ohio University was used for component testing [130].…”

The generation of dynamic high energy density plasmas in the pico-to nanosecond time domain at high-energy laser facilities affords unprecedented nuclear science research possibilities. At the National Ignition Facility (NIF), the primary goal of inertial confinement fusion research has led to the synergistic development of a unique high brightness neutron source, sophisticated nuclear diagnostic instrumentation, and versatile experimental platforms. These novel experimental capabilities provide a new path to investigate nuclear processes and structural effects in the time, mass and energy density domains relevant to astrophysical phenomena in a unique terrestrial environment. Some immediate applications include neutron capture cross-section evaluation, fission fragment production, and ion energy loss measurement in
