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

This paper describes a new system for quantitative measurement of multiphase flow. It is based on the use of high speed (50 frames per second) X-ray tomographic imaging. This requires a new X-ray tube concept to be implemented, together with an annular detector array and data acquisition system. A pressurised krypton microgap detector is being developed to give 90% quantum efficiency for detection of K/sub /spl alpha// radiation from the silver anode X-ray tube. Results from simulation work are presented to justify the overall design strategy selected.
