This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. Primary support for the subproject and the subproject's principal investigator may have been provided by other sources, including other NIH sources. The Total Cost listed for the subproject likely represents the estimated amount of Center infrastructure utilized by the subproject, not direct funding provided by the NCRR grant to the subproject or subproject staff. This project will evaluate the performance of a direct detection camera for use for single particle data collection for CryoTEM. A direct detection camera uses a radiation hardened CMOS detector for direct detection of electron. Since the camera does not have a scintillator, the MTF characterstics of the camera are significantly better than traditional CCD cameras. The project will experimentally assess this camera design for use for low dose, single particle data collection.

这个子项目是许多利用资源的研究子项目之一 由NIH/NCRR资助的中心拨款提供。子项目的主要支持 而子项目的主要调查员可能是由其他来源提供的， 包括其它NIH来源。 列出的子项目总成本可能 代表子项目使用的中心基础设施的估计数量， 而不是由NCRR赠款提供给子项目或子项目工作人员的直接资金。 该项目将评估用于单个探测器的直接探测相机的性能。 用于CryoTEM的粒子数据收集。 直接探测摄像机使用辐射硬化 用于直接检测电子的CMOS探测器。由于相机没有闪烁体， 该相机的MTF特性明显优于传统的CCD相机。 该项目将通过实验评估这种相机设计用于低剂量，单粒子 数据收集。
