Abstract
Предложено устройство для определения элементного состава образцов твердых или жидких материалов, содержащее нейтронный блок, выполненный с приемным сосудом для размещения в нем исследуемого образца материала и снабжённый: (a) нейтронным генератором, предназначенным для генерации потока меченых нейтронов и альфа-частиц, при этом в нейтронный генератор встроен альфа-детектор; (b) детекторами гамма-излучения, предназначенными для регистрации спектров характеристического гамма-излучения, возникающего при облучении образца материала потоком меченых нейтронов; (c) системой анализа данных, предназначенной для сбора и анализа данных, получаемых от альфа-детектора нейтронного генератора и детекторов гамма-излучения; и (d) биологической защитой нейтронного блока, обеспечивающей безопасную работу обсуживающего персонала, при этом система анализа данных выполнена с возможностью определения элементного состава образца материала с использованием только гамма-квантов, попадающих в выбранный временной интервал временного спектра альфа-гамма совпадений и соответствующих образцу материала, и с использованием другой части временного спектра альфа-гамма совпадений для энергетической калибровки полученных спектров гамма-излучения при каждом измерении каждого образца. Также предложен соответствующий способ, осуществляемый в предложенном устройстве.A device for determining the elemental composition of samples of solid or liquid materials is proposed, containing a neutron unit made with a receiving vessel for placing a sample of material in it and equipped with: (a) a neutron generator designed to generate a flux of tagged neutrons and alpha particles, while in a neutron generator built-in alpha detector; (b) detectors of gamma radiation, designed to record the spectra of characteristic gamma radiation that occurs when a sample of material is irradiated with a flux of tagged neutrons; (c) a data analysis system for collecting and analyzing data from the alpha detector of the neutron generator and gamma-ray detectors; and (d) biological shielding of the neutron unit, ensuring the safe operation of the maintenance personnel, while the data analysis system is configured to determine the elemental composition of the material sample using only gamma quanta falling within the selected time interval of the alpha-gamma coincidence time spectrum and corresponding to the material sample , and using the other part of the alpha-gamma coincidence time spectrum to energetically calibrate the obtained gamma-ray spectra for each measurement of each sample. Also proposed is a corresponding method implemented in the proposed device.
