Pulsed power accelerators compress electrical energy in space and time to provide versatile
experimental platforms for high energy density and inertial confinement fusion science. The …

Physical pictures for high energy density HED plasmas rely on models of the plasma
properties. For example, the inner structure of astrophysical plasmas such as stars is often …

Nearly a century ago it was recognized that radiation absorption by stellar matter controls
the internal temperature profiles within stars. Laboratory opacity measurements, however …

A new technique is described for the isochoric heating (ie, heating at constant volume) of
matter to high energy-density plasma states (<? format?>><? format?> 10 5 J/g) on a …

In the processes studied in contemporary physics one encounters the most diverse
conditions: temperatures ranging from absolute zero to those found in the cores of stars, and …

The first systematic study of opacity dependence on atomic number at stellar interior
temperatures is used to evaluate discrepancies between measured and modeled iron …

Measurements of iron-plasma transmission at 156±6 eV electron temperature and 6.9±1.7×
10 21 cm-3 electron density are reported over the 800–1800 eV photon energy range. The …

We have developed an experimental platform at the National Ignition Facility that employs
colliding planar shocks to produce warm dense matter with uniform conditions and enable …

The fourth international LTE opacity workshop and code comparison study, WorkOp-IV, was
held in Madrid in 1997. Results of this workshop are summarized with a focus on iron …

We report the creation of solid-density aluminum plasma using free-electron laser (FEL)
radiation at 13.5 nm wavelength. Ultrashort pulses were focused on a bulk Al target, yielding …
