| 330 | _aThe experimental results of studying the grazing interaction of microfocus bremsstrahlung with the edge surface of a plastic framework of the radiographic image quality standard Duplex IQI are presented. The results show that the edge contrast depends on the orientation of the edge surface and can be more complex than the two narrow bands of increased and decreased darkening on the X-ray radiographic pattern, which are determined by radiation refraction. The results were obtained using microfocus bremsstrahlung generated by grazing interaction of an internal electron beam of a B-18 betatron with an energy of 18 MeV with a surface of the Si target 50 or 8 μm thick and 4 mm long along the electron beam. The results are compared with the results on edge contrast obtained using the microfocus bremsstrahlung of a 450-keV X-ray tube with a focus size of 400 μm. | ||
