ОПТИЧЕСКИЙ МЕТОД ИЗМЕРЕНИЯ ЭНЕРГЕТИЧЕСКОГО СПЕКТРА НЕЙТРОНОВ НА ОСНОВЕ ГАЗОВОГО СЦИНТИЛЛЯТОРА
Журнал прикладной спектроскопии(2020)
摘要
The neutron energy spectrum is one of the most important characteristic parameters. A novel optical measurement method is proposed. The purpose of the method is to determine the neutron spectra according to the recoil proton track length. The recoil protons deposit energy along the track and excite scintillator luminescence. The luminescence image directly reflects the neutron energy spectra. The Geant4 simulation toolkit is used to study the characteristics of the recoil proton luminescence distribution and determine the detector system response. A reconstruction algorithm based on the potential reduction interior point is developed and applied to spectrum unfolding. This method has the advantages of an intuitive measurement, good energy resolution, suitability for various charged particle beams, a wide energy range, convenience, and an adjustable range.
