Problems solved by technology

However, most of the current multi-sphere systems use multiple moderating spheres of different sizes for measurement. In the case of a large demand or the need to carry equipment for on-site measurement, there is a large demand for materials such as device components and moderators, which is not conducive to the transportation, installation and use of the neutron spectrum measurement system

Abstract

The invention, which belongs to the technical field of neutron energy spectrum measurement, provides a neutron energy spectrum measuring system comprising a bracket, neutron detectors and N sphericalcavities sleeved layer by layer from the outside to the inside. The N is an integer greater than or equal to 2. The bracket includes a support base and a load-bearing column connected to the support base. The end portion of the load-bearing column extends into the geometric centers of the spherical cavities and is fixed with the cavity of the Nth spherical cavity; and the load-bearing column is connected with N-1 spherical cavities except the Nth spherical cavity. Each spherical cavity is formed by splicing of at least one sub cavity; and the adjacent sub cavities forming one same spherical cavity are fixed. The neutron detectors include a first neutron detector and / or second neutron detectors; the first neutron detector is arranged at the geometric center of the Nth spherical cavity; anda plurality of second neutron detectors are arranged and are distributed in a circumferential distribution of any spherical cavity. Therefore, the diversified detection demands can be satisfied; the detection equipment is highly integrated; the portability is high; and the application range is wide.

Description

technical field [0001] The invention relates to the technical field of neutron energy spectrum measurement, in particular to a neutron energy spectrum measurement system. Background technique [0002] Neutron energy spectrum is an important property of neutron source, and the measurement of neutron energy spectrum is very meaningful to the research of nuclear physics. For example, by measuring the energy spectrum of nuclear reactions that produce neutrons, information on nuclear energy levels can be obtained. In the field of neutron applications, neutron spectrum measurement is also very important. For example, the design and experiment of nuclear reactors and nuclear weapons need to know the fission neutron spectrum of fission elements, as well as the neutron spectrum in the power plant. When promoting the application of neutron sources, it is also necessary to know the neutron energy spectrum of the neutron source and the neutron energy spectrum in the experimental device...
