| description |
This paper presents the results of research on the application of the Monte Carlo simulation method
to investigate the dependence of neutron detection efficiency and neutron/gamma pulse discrimination
capabilities on the size of a detector using the EJ-301 scintillator, supporting the design
and development of neutron detectors. We constructed and evaluated eight cylindrical detector
models with varying lengths and diameters using the Geant4 toolkit. The simulated detector
models consist of a scintillator coupled with a light guide and a photomultiplier tube (PMT). The
simulated pulse signals obtained from each model were analyzed to assess neutron/gamma discrimination
using the digital charge integration (DCI) method, and neutron detection efficiency
was determined at various energy thresholds. The neutron/gamma discrimination results were
evaluated based on the Figure of Merit (FoM). The results showed that both neutron/gamma discrimination
and neutron detection efficiency are significantly dependent on the detector size, particularly
the variations in length and diameter. These findings are crucial for optimizing the design
of neutron detectors using organic scintillators like EJ-301 or similar materials, aiming to enhance
neutron/gamma discrimination and neutron detection efficiency. |
