SPECTROSCOPIC LINE SHAPE MEASUREMENTS AT HIGH DENSITIES

摘要

A comprehensive spectroscopic investigation of plasmas at extreme conditions produced by indirectly driven inertially confined implosions is described. In these exper- iments argon is doped into the gas filled core of implosion targets and the Ar K-shell emis- sion is used to make time resolved measurements of electron density and electron temperature. The electron density is derived from the Stark broadened Ar XVII 1s~2-1s3p line shape, the electron temperature is derived from the line intensity ratio of the Ar XVII 1s~2-1s3p transition and the lithium-like dielectronic satellites 2l2l′, 2l3l′ lying on the low energy side of the resonance line.
