Abstract
The fiber-optic neutron detector consists principally of a
neutron-sensitive scintillator, optical fiber, and photomultiplier
tube. It has features such as small size, real-time online
measurement capability, and high resistance to electromagnetic
interference. This detector is excellent for neutron detection in
areas with limited space and strong electromagnetic
interference. However, its small size results in a comparatively low
neutron sensitivity. The goal of this study is to look into the
relationship between detector parameters and performance in order to
improve the detector design. The research begins with the
development of a detector model using Monte Carlo simulation
programs to investigate the relationship between the
6LiF/ZnO:Ga mass ratio, thickness, wavelength-shifting fiber
length, and detector performance. The 6LiF/ZnO:Ga mass ratio
was then used as the test parameter to create equivalent detector
samples for experimental validation. The results show that the
detector has the highest neutron sensitivity when the mass ratio of
6LiF/ZnO:Ga is 1:1. This pattern is consistent with
theoretical simulation results, indicating that the optimization
strategy for detector parameters is feasible. The results of this
work give a theoretical foundation for the development and practical
implementation of the fiber-optic neutron detector.
