Development of a high speed X-ray tomography system for multiphase flow imaging

This paper describes a new system for quantitative measurement of multiphas e now. It is based on the use of high speed (50 frames per second) X-ray to mographic imaging. This requires a new X-ray tube concept to be implemented , together with an annular detector array and data acquisition system: A pr essurised,krypton microgap detector is being developed to give 30% quantum efficiency for detection of K-alpha radiation from the silver anode X-ray t ube. Results from simulation work are presented to justify the overall desi gn strategy selected.
