0736256VetterThis work will adapt and implement a Si-drift detector suitable for Compton imaging. The PIs will develop suitable algorithms based on the capability of this device which will accomplish Compton imaging based primarily on the energy deposition patterns of the Compton electron. They propose another effort beyond building and software development in which they would evaluate other electron tracking efforts. The project could benefit passive interrogation technology by providing a higher resolution, low noise detectors. For certain applications in Homeland Security and astrophysics, the use of additional source location information can significantly enhance detection efficiency. This would be enhanced by electron tracking as this would reduce the uncertainty in the location further and allow better background subtraction.

0736256vetter这项工作将适应并实现一个适合康普顿成像的硅漂移探测器。pi将根据该设备的能力开发合适的算法，该算法将主要基于康普顿电子的能量沉积模式来完成康普顿成像。他们提出了另一项超越建筑和软件开发的工作，他们将在其中评估其他电子跟踪工作。该项目可以通过提供更高分辨率、低噪音的探测器来受益于被动询问技术。在国土安全和天体物理学的某些应用中，使用额外的源位置信息可以显著提高探测效率。这将通过电子跟踪增强，因为这将进一步减少位置的不确定性，并允许更好的背景减去。
