ARI-MA: Gamma Ray Imaging of Special Nuclear Materials with a Liquid Xenon Time Projection Chamber

1039206麦肯锡该奖项将支持开发一种使用液体Xe的核和放射材料的高灵敏度被动成像探测器，以建造和测试康普顿伽马射线成像仪。液体Xe很容易获得，相对便宜，伽马射线探测效率大，能量和空间分辨率都很好。具有良好能量分辨率和成像能力的伽马射线探测器为远距离定位感兴趣的源提供了可达到的最高性能；其中包括1001keV和2614keV的高浓缩铀的使用。拟议的活动还包括对博士后、研究生和本科生进行探测器模拟、设计、制造和表征方面的培训。PI计划与公立学校的学生合作，包括高中、初中和一至六年级的学生。两相康普顿成像仪的开发有望提高液体氙气PET(LXePET)中伽马相机的位置和能量分辨率，从而更好地定位发射的恶性细胞。

1039206 McKinseyThis award will support the development of a highly sensitive passive imaging detector of nuclear and radiological materials using liquid Xe to build and test a Compton gamma-ray imager. Liquid Xe is readily available, relatively cheap, large gamma-ray detection efficiency, and excellent energy and spatial resolution. Gamma-ray detectors with good energy resolution and imaging capabilities offer the highest attainable performance for locating interesting sources at long range; these include the use of HEU for 1001 keV and 2614 keV.The proposed activities also include the training of postdocs, graduate and undergraduate students in detector simulation, design, fabrication, and characterization. The PIs plan to work with students at public schools, including students in high school, middle school, and first to six grade schools. The development of a two-phase Compton imager is expected to improve the position and energy resolution of gamma cameras used in liquid xenon PET (LXePET), which will result in better localization of the emitting malignant cells.
