Application of high-energy photon CT system with laser-compton scattering to nondestructive test

Abstract

A CT system using high-energy monochromatic photons is one of the best choices for nondestructive test of industrial products. We have developed a CT system for nondestructive test of industrial products using the laser-Compton photons, which were generated with an electron accelerator and conventional commercial laser system. We measured the profile, and found that they were a 0.8 -1.5 mm in diameter. We also applied the CT system to the nondestructive test of the concrete specimen, and successfully obtained the CT image.
