用于在保障应用中检测特殊核材料（SNM）的现有的基于中子的系统通常基于3He比例计数器，其需要相对大体积的气体（每个系统高达几千升）。由于严重的3He短缺，在不久的将来，需要一种替代中子探测技术。其他行业以及医疗、安全和研究领域对3He气体的需求也存在竞争。据估计，现在3He年需求总量约为65，000升
Existing neutron based systems used for the detection of Special Nuclear Material (SNM) in Safeguards application are typically based on 3 He proportional counters requiring relatively large volumes of the gas (up to several thousand liters per system). Because of the severe 3 He shortage, a replacement technology for neutron detection is required in the near future. There are competing demands for 3 He gas from other industries, as well as medical, security and research fields. It is estimated that the total 3 He annual demand is now approximately 65,000 liters
