DEVICE FOR MEASURING NEUTRON FLOW DENSITY OF NUCLEAR POWER PLANT IN TERMS OF BACKGROUND INTERFERENCE FROM GAMMA RAYS AND HIGH-ENERGY SPACE ELECTRONS AND PROTONS Russian patent published in 2017 - IPC G01T3/08 

FIELD: physics.

SUBSTANCE: device for measuring the neutron flow density of the nuclear power plant in terms of background interference from gamma rays and high-energy space electrons and protons, contains a neutron moderator, a power supply unit and two parallel semiconductor detectors coated with the neutron converter on the sensitive area of each detector, wherein the sensitive areas of the detectors coated with the converters are turned towards each other, wherein the plate of organic material is located between the detectors, and the signals from the detectors, passing through the registering channels individual for each detector, consisting of a charge-sensitive preamplifier, of the signal selection device according to the amplitude and the timestamp shaper, are fed to the time selection device working according to the anticoincidence scheme.

EFFECT: measuring the neutron flow density in terms of background interference from gamma rays and high-energy space electrons and protons.
