这是一份关于我们替代工作结果的简短总结白皮书：中子探测是为国土安全目的阻断放射性威胁的一个重要方面，因为钚是一种用于核武器的材料，是裂变中子的重要来源[Kouzes 2005]。由于最常用的中子探测器中使用的3He即将短缺，在不久的将来，大多数探测系统都需要中子探测的替代技术[Kouzes 2009 a]。对于国土安全应用，来自探测器的中子假警报可能导致显著的影响。这对任何中子探测技术提出了强烈的要求，即在仅存在大型伽马射线源的情况下不会产生错误的中子计数[Kouzes等人，2008]。
This is a short summary whitepaper on results of our alternatives work: Neutron detection is an important aspect of interdiction of radiological threats for homeland security purposes since plutonium, a material used for nuclear weapons, is a significant source of fission neutrons [Kouzes 2005]. Because of the imminent shortage of 3He, which is used in the most commonly deployed neutron detectors, a replacement technology for neutron detection is required for most detection systems in the very near future [Kouzes 2009a]. For homeland security applications, neutron false alarms from a detector can result in significant impact. This puts a strong requirement on any neutron detection technology not to generate false neutron counts in the presence of a large gamma ray-only source [Kouzes et al. 2008].
