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. A 100-element Ge detector array for XAS measurements was commissioned. The detector is for XAS measurements of ultra-dilute biological samples on SSRL?s beam line 9-3. It is based on 100 ea of 5 mm x 5 mm Ge detector elements fabricated as monolithic elements on one substrate crystal. They are therefore spatially arranged without any dead space in between, enhancing the collection area of the fluorescence signal. Significant integration work with electronics and associated software development is included in this project.

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。 一个100元素的锗探测器阵列XAS测量委托。 该探测器是用于XAS测量超稀释生物样品的SSRL？S光束线9-3。它基于100 ea的5 mm x 5 mm Ge探测器元件，作为单片元件制造在一个衬底晶体上。 因此，它们在空间上排列，其间没有任何死区，从而增强了荧光信号的收集区域。 与电子和相关软件开发的重要集成工作包括在这个项目中。
