9560332 Cao Quick and effective laboratory and field nondestructive evaluation of structural damage is important for earthquake studies. A conceptual design using the CSL high sensitivity, direct photon-electron conversion x-ray or gamma-ray image system is proposed to investigate a novel real-time nondestructive structural damage measurement technique. This new technique is to develop an x-ray or gamma-ray image detecting and processing system to directly visualize and quantify the structural damage, including damage location, damage pattern and sizes. A real-time assessment of the earthquake damaging process is also possible to be monitored by this fast respond x-ray or gamma-ray detector and the associated system. The proposed system can be used either in the Laboratory or in the field. During the proposed Phase I effort, CSL will work together with the National Center for Earthquake Engineering Research at Suny Buffalo to conduct a series of experiments to quantify the major design parameters of the system to prove the practicality of this novel technique. This research shall result in a portable, effective, low cost and easy to use x-ray or gamma-ray inspection system for structural damage assessment. This system will benefit both laboratory and field work, and reduce the cost of earthquake damage assessment significantly. The proposed research would lead to better understanding of structural damages caused by earthquake. The technique, once developed, offers a very useful tool for laboratory studies and field inspection, monitoring and measurement of earthquake damages. The proposed real-time, nondistortion, high spatial/temporal, and portable x-ray and gamma-ray system shall also help generate business opportunities for inspection and monitoring of public structures, utilities and component production.

小行星9560332 快速、有效地进行结构损伤的实验室和现场无损检测是地震研究的重要内容。提出了一种利用CSL高灵敏度、直接光电转换X射线或γ射线成像系统进行结构损伤实时无损检测的概念设计。这一新技术是开发一种X射线或γ射线图像检测和处理系统，以直接可视化和量化结构损伤，包括损伤位置，损伤模式和大小。地震破坏过程的实时评估也可以通过这种快速响应的X射线或伽马射线探测器和相关系统来监测。该系统既可用于实验室，也可用于现场。在拟议的第一阶段工作中，CSL将与位于纽约州立大学布法罗的国家地震工程研究中心合作，进行一系列实验，以量化系统的主要设计参数，以证明这种新技术的实用性。本研究的结果将是一个便携式，有效的，低成本和易于使用的X射线或γ射线检测系统的结构损伤评估。该系统将有利于实验室和现场工作，并大大降低了地震损失评估的成本。 建议的研究将导致更好地了解地震引起的结构破坏。该技术一经开发，将为实验室研究和现场检查、监测和测量地震灾害提供非常有用的工具。拟议的实时、无失真、高空间/时间和便携式X射线和伽马射线系统还将有助于为公共结构、公用事业和部件生产的检查和监测创造商业机会。
