0736061AhlenNew technologies with improved sensitivity will be needed to identify hidden nuclear weapons in order to protect the United States from this threat. This project will build a detector that will measure the direction and energy of recoiling nuclei produced in collisions with neutrons emitted by spontaneous fission from plutonium warheads. The detector will have improved sensitivity compared to other neutron detectors due to its ability to determine the direction of approach of the neutrons, thereby reducing significantly the backgrounds due to cosmic ray neutrons. This research will bring together graduate and undergraduate students and researchers in a unique way.

0736061阿伦将需要具有更高灵敏度的新技术来识别隐藏的核武器，以保护美国免受这种威胁。该项目将建造一个探测器，用于测量与钚弹头自发裂变释放的中子碰撞产生的反冲核的方向和能量。与其他中子探测器相比，该探测器将具有改进的灵敏度，因为它能够确定中子的接近方向，从而显著减少由于宇宙射线中子而导致的背景。 这项研究将以独特的方式汇集研究生和本科生和研究人员。
