Paper Abstract

In the recent years it has been demonstrated that computed tomography represents the most advanced imaging technique in the field of non-destructive testings. In this field, although x-ray based facilities still play a dominant role, neutron tomography can provide very good results for specific applications, such as the early detection of corrosion in metallic structures, due to the peculiarities of the neutron-to-matter interaction. Thus, x-ray tomography and neutron tomography can be considered as complementary rather than alternative techniques. In this aim, a multipurpose detection system which is able to perform x-ray as well as neutron examinations requiring no or little modifications has been developed. It is based on a multi- channel plate image intensifier, which is coupled to a thin radiation-to-light converter layer as the sensitive element and to a self-constructed CCD camera. The performances of the system are theoretically evaluated in terms of the modulation transfer function of its components, while experimental tests have been carried out by the visualization of sample objects when using either neutron or x-ray sources.
