Abstract

This article discusses the features of the collimation system of a tomograph for monitoring steel products by Compton backscattering. The analysis of the aperture functions of the scattering volume for the ring-type detector with different sizes of the pinholes of the primary and secondary collimators is carried out. The efficiency of using a ring type detector is shown. Recommendations to select pinhole sizes of the primary and secondary collimators are given. An indirect estimation of the possible scanning depth of steel products is given.
