Design and study of neutron fluence rate measuring device for neutron generator radiation field
In recent years,with the continuous development of nuclear technology,small deuterium-deuterium and deuterium-tritium neutron generators have been applied in many fields due to their advan-tages such as high neutron yield and safe operation.The traceability of neutron fluence rate of the neutron generator is very important.In this study,a neutron fluence rate measuring device was developed based on BF3 counters.The size of device was optimized based on Monte Carlo simulation for measuring neutron fluence rate in emitted from different neutron generator.The device was built based on simulated results,and was calibrated in the standard 241 Am-Be neutron source radiation field.The neutron fluence rate of a deuterium-tritium neutron generator was measured and analyzed with the developed device.
