Název v původním jazyce

Spatial Resolution of the Medipix-2 as Neutron Pixel Detector

Popis výsledku v původním jazyce

Nowadays promising digital detector systems such as Medipix are available and make possible real-time imaging with high sensitivity and broad dynamic range. 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 thermalneutrons. 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
