The application relates to a nuclear power plant neutron energy spectrum and direction measuring device, system and method, which comprises a packaging shell, the packaging shell comprises an upper shell and a lower shell, a detection module is arranged between the upper shell and the lower shell, the detection module comprises a support and a plurality of plastic scintillators, the support is used for fixing and spacing the plurality of plastic scintillators to shield neutrons, a first signal acquisition module is arranged between the upper shell and the detection module and is used for acquiring a first group of scintillation light signals generated by the plurality of plastic scintillators close to one end of the upper shell, and a second signal acquisition module is arranged between the detection module and the lower shell and is used for acquiring a second group of scintillation light signals generated by the plurality of plastic scintillators close to one end of the lower shell. The application can realize simultaneous measurement of neutron energy spectrum and direction, has the advantages of lightness, radiation resistance and real-time monitoring, and is suitable for nuclear power neutron energy spectrum and direction measurement.

The application discloses a dielectric constant microwave sensor with a microstrip coupling line structure and particularly relates to the technical field of microwave sensing, and comprises a metal transmission line on an upper layer, a dielectric substrate on a middle layer and a grounded metal plate on a bottom layer; a signal path of the upper layer structure of the microwave sensor is arranged between the first port and the second port, and the signal path is composed of at least one transmission line, four coupling lines and two metalized through holes. The microstrip coupling line structure adopted in the application is sensitive to changes in the dielectric constant of external materials, has the advantages of small size, easy processing, low cost, high precision and the like, different sizes of the microstrip coupling line provide two measurement working frequency bands, and the microwave sensor can be effectively applied to solid dielectric constant measurement work.
