Abstract: A dual mode tomograph for three-component flow imaging has been built in a cooperative project between the University of Bergen, Christian Michelsen Research AS and Norsk Hydro AS. It is based on an eight-electrode capacitance tomograph and a gamma-ray tomograph with five radiation sources and 85 compact detectors. Embedded Transputers using memory-mapping ensure high speed data acquisition. An Alpha AXP system will be used as an on-line reconstruction unit. The tomographs have so far been tested and characterized as separate systems only. The first test results, however, demonstrate that it is feasible to do three-component flow regime identification at rates above 10 frames/s.
