Abstract

Results of developing and testing a betatron-based tomograph with an energy of up to 10 MeV are presented. The tomograph allows investigating objects with a shined-though thickness of up to 250 mm in steel equivalent. In contrast to foreign analogs, a horizontal product arrangement is used; it creates the most favorable conditions for revealing such defects as cracks and delaminations, since in this position, the product is subjected to small deformations due to gravitational forces. The proposed scanning scheme has the properties of a third-generation tomograph and preserves the quality of the tomogram and the time it is gathered with a reduced number of detectors and tomograph dimensions. The results of evaluating the tomograph sensitivity with a test sample and the results of testing products containing defects are provided.
