Fast neutron dosemeter using pixelated detector Timepix

Document available in abstract form only. Full text of publication follows: The pixelated detector Timepix is a unique detector of ionising particles with high position sensitivity. It provides additional information about the type of detected particle using pattern recognition analysis of clusters created from affected pixels. The 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. First results of such a dosemeter calibrated for monoenergetic neutrons in the energy of 0.4-16.5 MeV are presented. (authors)
