BF3 BF3 neutron detection system with self-diagnosis function and its method

摘要

The present invention relates to a BF3 neutron measurement system and method thereof, and more particularly, to a BF3 neutron measurement system and a method thereof capable of self-diagnosing a change in sensitivity of a neutron measurement system and a failure of a measurement instrument, The system includes a neutron measurement system for detecting neutrons using a BF3 fill gas, the system comprising: a multi-channel analyzer (110) for acquiring a signal detected by a BF3 detector; The multi-channel analyzer 110 measures the number of neutron energies as reference coefficients, stores the measured reference distribution, and analyzes the system health from the relationship between the reference distribution and the measurement distribution. Module 120; An input unit 130 for inputting variable information to the analysis module 120; And an output unit 140 for outputting diagnostic analysis results of the analysis module 120.
