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.

1039206 McKinsey该奖项将支持开发一种高灵敏度的核和放射性材料被动成像探测器，使用液体放射性物质来构建和测试康普顿伽马射线成像仪。液体探测器容易获得，相对便宜，伽马射线探测效率高，并且具有优异的能量和空间分辨率。 伽马射线探测器具有良好的能量分辨率和成像能力，提供了最高的可达到的性能定位感兴趣的源在长距离，其中包括使用高浓缩铀为1001千电子伏和2614千电子伏。拟议的活动还包括培训博士后，研究生和本科生在探测器模拟，设计，制造和表征。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PET（LXePET）中使用的伽马相机的位置和能量分辨率，这将导致更好地定位发射恶性细胞。
