Abstract

<p>A glass capillary plate (CP) gas detector is a hole-type micro pattern gaseous detector (MPGD). A hole-type MPGD typically consists of a thin insulator sheet (0.05–2 mm thick) with a large number of small holes (0.01–1 mm diameter). We have successfully developed an optical imaging CP gas detector, which consists of a CP gas detector, a mirror, and a cooled CMOS camera system, for neutron imaging. Its performance was investigated using a thermal neutron beam at KUANS. Owing to the high imaging capability of the optical imaging CP gas detector, tracks of α-rays or 7Li produced by the interaction between neutrons and 10B were clearly observed. We report on the properties of the optical imaging CP gas detector as a neutron imager and describe the outlook for future developments on the basis of the results of Monte Carlo simulations.</p>
