Abstract

A capillary plate (CP) gas detector is a type of a hole-type micropattern gaseous detector. The detector displays high spatial resolution characteristics in two-dimensional radiation detection by using a CP with a small channel pitch. In this study, a sealed-type CP gas detector for neutron imaging was developed. The detector converts the incident position of neutrons to an optical image. A novel imaging system was constructed, and it comprised the CP gas detector, an image intensifier unit, and a science-CMOS camera. The system was tested with a compact accelerator driven neutron source, “KUANS.” Each signal of charged particles generated by a nuclear reaction between a neutron and a 10B layer was obtained. The results indicated that neutron images were obtained clearly.
