越来越多地使用X射线吸收光谱(边缘和EXAFS)来确定生物分子活性位点的局部结构,引起了人们对X射线损伤性质和样品完整性的更大兴趣和关注。作为补充,需要从样品中有效收集X射线光子,以最大限度地提高数据采集并最大限度地减少样品损坏。本报告介绍了斯坦福大学同步辐射实验室和康奈尔大学高能同步辐射源目前使用的系统,包括两种类型的低温技术的样品保护和快速X射线光子探测的大立体角收集。
Increasing use of X-ray absorption spectroscopy (edge and EXAFS) to determine the local structure of active sites of biological molecules has caused greater interest in and attention to the nature of X-ray damage and the integrity of the sample. In a complementary way, efficient X-ray photon collection from the sample is required in order to maximize data acquisition and minimize sample damage. This report describes systems currently in use at Stanford Synchrotron Radiation Laboratory and Cornell High Energy Synchrotron Source, comprising two types of low-temperature techniques for sample protection and fast X-ray photon detection of large solid-angle collection.
