The high radiodensity of the krypton gas enables non-intrusive volumetric measurements of gas density and mixture composition based on spatial variations in X-ray attenuation. Comparisons of these measurements to both computational results from large-eddy simulations and data from previous experiments are presented, and the viability of this diagnostic technique is assessed. Important aspects of X-ray attenuation theory, XCT practice, and relevant error analysis are considered in data processing, and their impacts on the future development of this technique are discussed.
