0736123KarwowskiA number of techniques are being developed to detect nuclear materials in large cargo containers are based on using gamma-ray (ã-ray) beams to identify specific isotopes by the detection of emitted gamma-rays and/or neutrons. High intensity ã-ray beams with good energy resolution are expected to generate acceptable radiation doses to cargo and to enable scans to be performed in short enough times that make these techniques viable solutions. An ultimate goal is to apply this technology as the basis for systems that make isotope-specific images of high-Z materials in cargo containers. The proposed collaborative research will provide nuclear data and develop measurement techniques relevant to the mission of the DNDO to develop technologies for nuclear threat detection. Several undergraduate and graduate students will be involved, including two graduate students from North Carolina Agricultural & Technical State University, an historically black university.

卡沃夫斯基正在开发一些技术来探测大型货物集装箱中的核材料，这些技术的基础是使用伽马射线束通过探测发射的伽马射线和/或中子来识别特定的同位素。具有良好能量分辨率的高强度射线束预计将对货物产生可接受的辐射剂量，并能够在足够短的时间内进行扫描，从而使这些技术成为可行的解决方案。最终目标是将这项技术作为系统的基础，在货物集装箱中制作高Z材料的同位素特定图像。拟议的合作研究将提供核数据并开发与DNDO开发核威胁探测技术的任务相关的测量技术。几名本科生和研究生将参与其中，其中包括两名来自北卡罗来纳农业与技术州立大学的研究生，这所大学是一所历史悠久的黑人大学。
