Detailed Measurements of Line Shape, Line Shift, and Sel-Absorption Effects on Stagnation Enthalpy Measurements Using the Copper Line Intensity Ratio Technique.

摘要

Spectral line intensities, line widths, and shifts of the copper lines at 5106 Angstrom and 5153 Angstrom were obtained while viewing the gas cap radiation from models in an arc-heated nozzle flow. These spectral features were then used to infer the enthalpy and copper density of the gas in the model stagnation zone.
