Abstract
Experimental results of determining the resolution of radiography using the bremsstrahlung from the improved compact SEA-7 betatron with electron energy of 7 MeV are presented. Measurements were made using AGFA NDT D4 PbVacuPac X-ray films and Duplex IQI image quality indicator (model EN 462-5). The obtained results demonstrate a different resolution (approximately 0.16 mm) of thin wire pairs of the indicator in different areas of the radiation cone, i.e., a different horizontal size of the effective radiation focus (approximately 0.2 mm), which must be taken into account when analyzing radiographic images of real objects. The vertical size of the radiation focus (approximately 1.4 mm), which is perpendicular to the plane of the electron orbit, was also estimated.
期刊介绍：
Instruments and Experimental Techniques is an international peer reviewed journal that publishes reviews describing advanced methods for physical measurements and techniques and original articles that present techniques for physical measurements, principles of operation, design, methods of application, and analysis of the operation of physical instruments used in all fields of experimental physics and when conducting measurements using physical methods and instruments in astronomy, natural sciences, chemistry, biology, medicine, and ecology.
