Polar direct drive neutron source experiments were performed at the National Ignition
Facility showing substantial improvement in total neutron yield and efficiency of conversion …

A new time-resolved opacity spectrometer (OpSpecTR) is currently under development for
the National Ignition Facility (NIF) opacity campaign. The spectrometer utilizes Icarus version …

X-ray opacity is a crucial factor of all radiation-hydrodynamics calculations, yet it is one of the
least validated of the material properties in the simulation codes. Recent opacity …

Direct drive implosions of plastic capsules have been performed at the National Ignition
Facility to provide a broad-spectrum (500–2000 eV) X-ray continuum source for X-ray …

This paper discusses the modeling of experiments that measure iron opacity in local
thermodynamic equilibrium (LTE) using laser-driven hohlraums at the National Ignition …

The opacities of iron and other mid-Z elements help to regulate the transport of energy in the
sun. Recent experiments on the Sandia National Laboratories Z machine have shown large …

Recent experiments at the Sandia National Laboratory Z facility have called into question
models used in calculating opacity, of importance for modeling stellar interiors. An effort is …

Extreme radiative phenomena, where the radiation energy density and flux strongly
influence the medium, are common in the universe. Nevertheless, because of limited or …

Discrepancies exist between theoretical and experimental opacity data for iron, at
temperatures 180–195 eV and electron densities near 3× 1022/cm3, relevant to the solar …

Laboratory (laser and Z-pinch) opacity measurements of well-characterized plasmas provide
data to assist inertial confinement fusion, astrophysics and atomic-physics research. In order …
