The Introscopy Institute of Tomsk Polytechnical University (SRII of TPU) is a large institution established with the goal of developing and designing nondestructive testing (NDT) systems for industrial application. The traditional direction in this field is related to the fabrication of mobile NDT systems using small-size betatrons. Up to the present, SRII continues to produce small-size betatrons with a maximum energy from 4 to 10 MeV.
