Title:
NEUTRON BEAM DETECTION DEVICE, NEUTRON BEAM DETECTION METHOD AND NEUTRON BEAM DETECTION PROGRAM
Document Type and Number:
Japanese Patent JP2022115849
Kind Code:
A
Abstract:
To provide a small-sized neutron beam detection device, a neutron beam detection method and a neutron beam detection program.SOLUTION: A neutron beam detection device comprises: a solar cell type detector having a surface with a conversion membrane for converting a neutron to a charged particle beam or a photon, and generating a current by the incident of a radiation; a radiation detector for setting a current having no sensitivity to the neutron as an output signal by the incident of the radiation; an ammeter for detecting a current generated by the solar cell type detector, and a current generated by the radiation detector as signals; and a flux calculation unit for comparing current signals from the detectors which are detected by the ammeter. The flux calculation unit makes the current signals from the solar cell type detector and the radiation detector correspond to a relationship between a flux of the incident radiation related to a pre-acquired prescribed beam type and detection currents from the solar cell type detector and the radiation detector, and calculates a flux of the neutron.SELECTED DRAWING: Figure 1
