Abstract

Abstract

Personal neutron dosimetry is of great significance to the staff of nuclear facilities such as nuclear power plants, nuclear power units, research reactors and high-energy accelerators. Optically stimulated luminescence (OSL) technique has the advantages of fast reading speed and repeated reading many times, and is an important development direction of neutron personal dose monitoring. In this paper, a dual-sided trench shaped optically stimulated luminescence neutron detector (DS-TSOSLND) using ⁶LiF/α-Al₂O₃:C is designed, and the Monte Carlo code Geant4 is used to calculate and analyze the influences of different trench width, depth and trench ratio on the detector performance, so as to explore its neutron detection mechanism. Based on the simulation results of Geant4, DS-TSOSLND was successfully developed by combining the current processing conditions of α-Al₂O₃:C crystal microstructure. The test results of ¹³⁷Cs source and heavy water moderated ²⁵²Cf neutron source show that the neutron detection threshold of the newly developed DS-TSOSLND is 10.3 μSv, and the neutron dose response is linear in the range of 0.05~20 mSv, which has broad application prospects in the field of personal neutron dosimetry.
