PHOTOGRAPHIC RESPONSE TO X-RAY-IRRADIATION .3. PHOTOGRAPHIC LINEARIZATION OF BEAM-FOIL SPECTRA

In this paper models for the relation of specular density to incident (x-ray) intensity with uncertainties are applied to experimental data, indicating methods for the correction of additional effects. Lineariz ation and error calculations are simplified by double linear interpola tion, and the effect of this is quantified. Relative first-order inten sities are determined directly. Secondary linearization or calculation for higher-order lines gives correction factors that yield absolute a nd relative higher-order intensity ratios. The effects of energy and a ngle on linearization are included. Densitometry uncertainty is estima ted and quantified.
