Neutron imaging at PSI: a promising tool in materials science andtechnology

Neutron imaging as a method for non-destructive studies takes advantage of the alternative contrast mechanism of neutrons compared to X-rays: most of the light elements feature high contrast, whereas heavy elements are relatively transparent to neutrons. In the previous decade, the neutron imaging technique has made substantial progress in well-tailored and well-equipped beam lines, in improvements of the image recording quality and efficiency by new and modern imaging techniques, and in modern image processing tools. This article gives an overview of PSI's activities in this promising and still developing field combining high potential as research tool and as technique for industrial investigation and non-destructive testing. Examples are chosen from the fields of energy and mobility and inspection of highly activated samples. Furthermore, recent developments in phase contrast imaging and energy selective imaging studies are highlighted. Finally, future trends in neutron imaging are addresse
