Peak core temperature is an important measure of implosion performance, and will be a critical diagnostic of ignition implosion performance at the National Ignition Facility because peak temperatures must attain high values in order to form the hot-spot spark that ignites the main mass of deuterium-tritium fuel. We plan to measure peak core temperatures, resolved in space and time, using a gated pinhole...
Summary form only given. We have implemented a wide variety of charged-particle diagnostics on OMEGA, including magnet-based spectrometers (CPS); wedge-range-filter-based spectrometers (WFR); proton core image system (PCIS); proton radiography; and proton temporal diagnostics (PTD). Recent work has resulted in the comprehensive measurements of spatial-, temporal- and spectral- resolved energetic charged...
Summary form only given. Results from the first NIF indirect-drive ICF experiments and Omega experiments testing new hohlraum and capsule designs are described. In the area of laser-hohlraum coupling, the effects of laser beam smoothing by spectral dispersion (SSD) and polarization smoothing (PS) on the beam propagation in long scale gas-filled targets has been studied at NIF at plasma scales relevant...
