Methods for Determining the Electron Density of a Laser Plasma from X-Ray Spectra of Multiply Charged K Ions

摘要

A description is given of present methods of determination of the electron density of laser plasma from x-ray line spectra of multiply charged K ions. The paper describes the body of experimental results and their comparative analysis, and the potentialities of various methods. The methods discussed are based on measurements of (1) the intensity ratio of the resonance and intercombination lines of (He) ions, (2) intensity ratio of two-electron satellites of the resonance doublet Ly/sub alpha / of (H) ions, (3) intensity ratio of the fine splitting components of Ly/sub alpha / of (H) ions in an optically thin plasma, and (4) Stark broadening of the spectral lines of (H) ions.
