Abstract

Progress in the development of neutron imaging facilities requires more sophisticated and advanced tools for high resolution and efficient neutron detection. This paper reports on the evaluation of CMOS Monolithic Active Pixel Sensor (MAPS) technology as a neutron detector. The sensor HEPAPS4, which was originally designed for high energy physics applications, was coated with two types of conversion material. The ⁶LiF converter is suitable for the detecting thermal neutrons, while the polyethylene converter is used for the tracking fast neutrons. The results showed that such a technology is suitable for the detection of both fast and thermal neutrons.
