Plasma Radiation Sources. Quasi-Adiabatic Theory and Numerical Modeling in the Electro-Diffusive Approximation

摘要

This report describes work done under DNA Contract 001-79-C-0189 from February 1982 to June 1983, and some more recent work. Part I includes treatments of a simple zero-D implosion code, analytic but very approximate scaling laws for radiation, and a discussion of preliminary work on nonlinear field penetration of plasma. Part II contains a discussion of electrodiffusive 1D modeling of annular plasma implosions. The thermoelectrical field, its role in field penetrations, the nonlocal constraints required in field diffusionn (and some arising from field diffusion), flux limits and the acceleration process for annular plasmas are discussed.
