Протоны отдачи выделяют энергию вдоль трека и возбуждают люминесценцию сцинтиллятора. Изображение люминесценции напрямую отражает энергетические спектры нейтронов. Набор инструментов моделирования Geant4 используется для изучения характеристик распределения люминесценции протонов отдачи и определения отклика детекторной системы. Разработан алгоритм восстановления, основанный на внутренней точке потенциальной редукции, который применяется для развертки спектра. Метод обладает преимуществами интуитивного измерения, хорошего разрешения по энергии, пригодности для различных пучков заряженных частиц, широкого диапазона энергий, удобства и регулируемого диапазона.</p></abstract><trans-abstract xml:lang="en"><p>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.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>оптический метод</kwd><kwd>энергетический спектр нейтронов</kwd><kwd>газовый сцинтиллятор</kwd><kwd>разворачивание</kwd></kwd-group><kwd-group xml:lang="en"><kwd>optical method</kwd><kwd>neutron energy spectrum</kwd><kwd>gaseous scintillator</kwd><kwd>unfolding</kwd></kwd-group><funding-group><funding-statement xml:lang="en">Financial support from the Opening Foundation of State Key Laboratory of Intense Pulsed Radiation Simulation and Effect are gratefully acknowledged</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">N.
