Název v původním jazyce

Detector Timepix as a dosemeter of fast neutrons

Popis výsledku v původním jazyce

The pixelated detector Timepix is an unique detector of ionising particles with high position sensitivity. It provides an additional information about the type of detected particle using pattern recongnition analysis of clusters created from affected pixels. A Timepix detector covered with polyethylene convertors of different thicknesses is presented as a real-time dosemeter for measuring dose equivalents in fast neutron fields of unknown spectra. The application of such a dosemeter could be found in the control rooms of nuclear power plants, in research accelerators or for neutron dose estimation in proton therapy centres. The way of creating such a dosemeter is to apply different weighting factors on the collected signal from identified recoiled protons under particular convertors. We are presenting the first results of such a dosemeter calibrated under monoenergetic neutrons in National Physics Laboratory. An energy of neutron beam is in range 0.5-16.5 MeV. The results are compared
