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. Good performance of a neutron detecting device is essential for the acquisition of high quality neutron images. Slow neutrons are captured and converted in a thin layer containing Li-6 to tritons and alpha particles which are subsequently detected by a silicon pixel detector Medipix-2. The detector performance was tested at the NEUTRA station of the Paul Scherrer Institute using a beam of slow neutrons. 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. The system is very promising in applications for micro-neutron tomography
