Properties of Neutron Pixel Detector Based on Medipix-2 Device

Popis výsledku v původním jazyce

The neutron transmission radiography can serve as complementary diagnostic method to the X-ray radiography. It can produce contrast images of materials, which are indistinguishable in X-ray images. The properties of the neutron pixel detector based on the single X-ray photon pixel detector device Medipix-1 were already published. 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. A Medipix-2 detector (256 x 256 square pixels with pitch of 55 um) was adapted similarly. The detector performance was tested at the NEUTRA station of the Paul Scherrer Institute. The spatial resolution, detection efficiency and other detector properties were determined and compared with several types of contemporary neutron imaging systems. The results demonstrate superior state of the Medipix-2 based neutron imager in terms of the spatial resolution, linearity and dynamic range.
