The properties of the neutron pixel detector based on the single X-ray photon pixel detector device Medipix-2 (Silicon sensor, 256 x 256 square pixels with pitch of 55 um) were determined. Slow neutrons are captured and converted in a surface layer containing Li-6 to tritons and alpha particles which are subsequently detected by a silicon pixel detector. The spatial resolution, detection efficiency and other detector properties have been determined and are compared with several types of contemporary neutron imaging systems.
