Consideration of the Neutron Image Intensifier Camera

Abstract

Several detectors have been developed for neutron transmission imaging, but neutron image intensifier (NII) is also an option in terms of field of view and sensitivity. Since NII has a position resolution of less than 0.1 mm, it can be expected to obtain a high-sensitivity, high-gradation fine image with a camera to be combined. In this research, we selected CMOS cameras for industrial applications with linearity in sensitivity as the camera, and examined the performance evaluation of the camera, especially the cooling effect of the sensor which becomes a problem in long time measurement. Based on this result, we developed a portable imaging system that compactly integrates a cooled camera with NII and camera and constructed a system that can be used instantaneously in various facilities.
