用于Cosmic Ray土壤水分监测的闪烁中子探测器的优化
Optimising Scintillating Neutron Detectors for Cosmic Ray Soil Moisture Monitoring
摘要:
宇宙射线中子传感(CRNS)是一种功能强大的技术,可以在与农业应用相匹配的长度尺度上对土壤水分进行非侵入性监测。限制在工业化农业环境中使用该技术的一个因素是通常用于地面中子监测的氦-3或BF 3管的初始成本高。本文讨论了Geant 4的使用,以优化一种替代闪烁体为基础的中子探测器,可能适用于成本是一个更高的驱动因素比时间分辨率的挑战。
英文摘要:
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.
