“…A great number of 6 Li-based neutron detection scintillators ( 6Li-glass, 6 LiI:Eu, 6 LiF/ZnS:Ag etc.) have been exploited [51,52]. However, the 6 Li-glass shows a low light yield of 6000 ph/neutron due to severe scintillation quenching.…”

Scintillation detection has attracted great interest in nuclear medicine, nuclear radiation detection, high-energy physics, and non-destructive inspection. The elpasolite crystals with Ce3+ dopants are promising for these endeavors due to their modest light yield and extremely good proportionality when excited by the gamma ray. Moreover, the 6Li and 35Cl isotopes in elpasolite crystals endow them with excellent neutron detection capability. These features allow not only a high energy resolution but also a high detection sensitivity. The elpasolite scintillators also enable the precisely dual detection of gamma/neutron signals through pulse height discrimination (PHD) or pulse shape discrimination (PSD). In this work, we review recent investigations on using the typical elpasolite scintillators, including Ce3+-doped Cs2LiYCl6 (CLYC), Cs2LiLaCl6 (CLLC), and Cs2LiLaBr6 (CLLB), for the monitoring of gamma rays and neutrons. The scintillation properties, detection mechanism, and elpasolite crystal structure are also discussed with the aim of improving high-energy ray detection ability.

“…This system was found to have neutron detection efficiencies of approximately 55% that of a typical Helium-3 based CRS1000 neutron detector. This presents a promising first step in developing scintillator based alternatives to Helium-3 in the CRNS agriculture sector, as there exists extensive prior work in the development and optimisation of Li 6 F:ZnS scintillators [20,21], their associated trigger systems [22,23], and correlations between muon and neutron cosmic ray intensities [24][25][26].…”

A: Cosmic Ray Neutron Sensing (CRNS) is a powerful technique that allows non-invasive monitoring of soil moisture on length scales well matched for agricultural applications. One factor limiting the use of the technique within industrial agriculture settings is the high initial cost of Helium-3 or BF3 tubes typically used for ground level neutron monitoring. This paper discusses the use of Geant4 to optimise an alternative scintillator based neutron detector that may be applicable for challenges where cost is a higher driving factor than temporal resolution.

Cosmic Ray Neutron Sensing (CRNS) is a powerful technique that allows non-invasive monitoring of soil moisture on length scales well matched for agricultural applications. One factor limiting the use of the technique within industrial agriculture settings is the high initial cost of Helium-3 or BF3 tubes typically used for ground level neutron monitoring. This paper discusses the use of Geant4 to design and optimise an alternative scintillator based epi-thermal neutron detector that may be applicable for challenges where cost is a higher driving factor than temporal resolution.
