Inference of electron density in NIF capsules from krypton helium-β Stark lineshapes

POSTER

Abstract

The dHIRES x-ray spectrometer measures Kr Heα and Heβ spectra from NIF compressed capsules with 10-eV spectral and 30-ps temporal resolution. Theoretical calculations of the Stark-broadened lineshape of the Heβ complex (3 3P1, 1P1, 1D2) show monotonic variations with density of the line widths, line energies, and intensity of the 3 3P1 and 3 1D2 lines relative to the main, 3 1P1 peak. Comparison of the measured Kr Heβ complex line profiles with the theoretical lineshapes provides a measure of the time history of the electron density. These comparisons will be shown for four NIF shots with Kr-doped capsules
