Abstract
Nowadays, ionizing radiation beams with relatively large transverse dimensions are widely used not only for research purposes but also in technological processes related to metal and food treatment, as well as medical instrument sterilization. Thus, control of beam characteristics is required, and in particular, the intensity distribution in the transverse plane must be accurately measured. The multiangle scanning method, based on mathematical transformations, allows overcoming the limitations of modern detectors used for these purposes. In this study, the method was applied to an electron beam. A detection system based on scintillating fiber was used. The beam profile was measured using the proposed method and a conventional detector — a film dosimeter. Experimental results allow to conclude that the beam intensity distribution obtained using the multiangle scanning method is close to the results obtained using a film dosimeter, which is most often used in medical institutions. Thus, we can consider the multiangle scanning method as an effective approach for determining the intensity distribution of an electron beam.
