A Study of Equations of State/Opacity of Ionized Gases.
Abstract
The report describes additions and modifications to the CAPO system of opacity codes and presents the results of other research tasks on emission, absorption and transport of radiation in high temperature materials. The accuracy of several approximate methods of opacity treatment is assessed. The radiative properties of thin plasmas, not in local thermodynamic equilibrium (non-LTE) are considered. Several codes written to provide ionic charge distributions, excited state populations, and emission rates in non-LTE plasmas are described. Electron positron pair production rates are studied and estimates made of the times required to establish significant pair populations under various conditions. (Author)
