The detector can be adapted for neutron detection by deposition of a converter layer to its surface. Thermal neutrons are converted in the layer into secondary radiation which can be subsequently detected by the pixel detector. The Medipix-2 device was tested as a neutron detector with different types of converters using a collimated beam of thermal neutrons. Converter materials were examined with aim to reach maximal spatial resolution at reasonable detection efficiency. Several images of real objects demonstrating the capabilities have been examined. The performance of the imager was compared with several types of contemporary neutron imaging systems. The results demonstrate superior properties of the Medipix-2 based neutron imager in terms of spatial resolution, linearity and dynamic range Workplace Institute of Theoretical and Applied Mechanics Contact Kulawiecová Kateřina, kulawiecova@itam.cas.cz, Tel.: 225 443 285 Year of Publishing 2006
