Analysis of fusion neutron spectral widths in high-foot implosions at the National Ignition Facility

We present the latest results of thermal temperature analyses of cryogenically layered deuterium-tritium implosions at the NIF using data from the ``High Foot'' campaign.\footnote{Hurricane, O. et al., Phys. Plasmas, {\bf 21} 056314 (2014)} Data from new analysis methods\footnote{Hatarik R. et al., Hartouni, E. et al. these proc.} and interpreted in the context of new theoretical developments\footnote{Munro D. et al. and Field, J. et al. these proceedings} will be reported. These data will include DD and DT apparent ion temperatures, their uniformity with direction, inferred plasma thermal temperature, as well as the magnitude of non-thermal contributions to the spectral widths.
