<title>Laser-Compton photon radiography for nondestructive test of bulk materials</title>

Abstract

Experimental results of transmission photon radiography of bulk materials using the laser-Compton photon beam in the energy range of 2 -20 MeV are given. The purpose of this work is to demonstrate the effectiveness and to survey a potential need and a technical limit of the present method for industrial application, such as nondestructive test of bulk materials. Several radiographs of metals, ceramics, and concrete were measured with the present method. Position resolution of the system was measured with using 10 MeV photon beam and slit. It was less than 1 mm.
