A dual mode tomograph for three-component flow imaging has been designed and is being built in a cooperative project between the University of Bergen, Christina Michelsen Research AS and Norsk Hydro AS. It is based on an eight-electrode capacitance tomography and a γ-ray tomograph with five radiation sources and 85 compact detectors. Embedded Transputers using memory-mapping ensure high speed data acquisition into the transputer-based reconstruction unit. The quality of the reconstructed imges from the capacitance system is improved by the use of new reconstruction algorithms. New efficient γ-ray detectors enable real-time flow imaging. The first tomograms from the capacitance tomograph demonstrate its good capability for flow regime identification. The first test results of the γ-ray detector system show a fairly good energy resolution (about 10 keV FWHM) even at high count rates (around 1 MC s−1). |
