Thanks to different values of neutron and X-ray attenuation coefficients in matter, neutronography can produce contrast images of materials, which are roentgenographically. Nowadays promising digital detector systems such as Medipix are available and make possible real time neutronographic imaging with high sensitivity and high dynamic range. A neutron pixel detector based on a single X-ray photon counting pixel detector device Medipix-1 is presented (64 x 64 pixels, each 170 x 170 m). Thermal neutrons are converted in a converter layer to the heavy charged particles, which are subsequently detected by the Medipix-1 device. Spatial resolution, detection efficiency and other detector properties are determined and compared with Monte-Carlo simulations. Results of studies of device sensitivity to background gamma radiation and to its activation by thermal neutrons are presented." . "2004" . .
