Ultraschnelle Elektronenstrahl-Röntgentomographie

The electron beam is commonly used as a unique tool for welding of metal parts, curing and polishing of product surfaces, or sterilisation of goods. In such cases the energy of the beam is used to modify a material. A sideproduct of is X-ray radiation which is considered a hazardous side effect of the processing. However, the X-ray radiation generated by an electromagnetically steered electron beam can also be used for X-ray imaging. Thus, a sophisticated imaging technique is electron beam X-ray computed tomography that has now for more than 20 years been used in cardiac diagnostics. Our group at Institute of Safety Research at FZ Rossendorf uses this technique to perform tomography on multi phase flows. The presentation will introduce the concept that is behind this technique and demonstrate its application on industrially relevant applications.
