SPECTROSCOPY ON X9B COMPUTER HARDWARE & SOFTWARE

该子项目涉及向NIH提交SIG申请 申请一种先进的X射线光谱阵列探测器， 比我们现有的探测器快3倍。 最近有所改善 在束线X9B中，使得当前XAS实验效率低下。 四折 现在可用于XAS实验的X射线通量增加， 由现有XAS的陈旧电子设备充分处理 检测器 XAS是NIH资助的每个项目的主要组成部分。 在提案中列出的7个主要用户中。 这些用户有13个NIH 将从该工具中受益的赠款。 这些用户还拥有 在过去三年中，使用该设施的XAS出版物超过60种 和资源中心的当前检测器。 此外，这些主要 Husers确定了18个NIH资助的合作者（另有20个NIH （与提案相关的资助项目）谁将从 获得该仪器。 XAS的可用射束时间 HX9B光束线的订购量是原来的两倍。 这些NIH资助的用户 他们的合作者几乎没有其他选择来完成他们的任务。 实验方案。 将吞吐量提高三倍 使用新的工具将是一个非凡的好处， 富有成效且资金充足的用户社区。

This sub-project involved submission of an SIG application to NIH requesting an Advanced Array Detector for X-ray spectroscopy that can count 3 times faster than our existing detector. Recent improvements in beamline X9B make current XAS experiments inefficient. The 4 fold increased x-ray flux now available for XAS experiments cannot be adequately handled by the antiquated electronics of the existing XAS detector. XAS is a major component of the NIH funded programs of each of the 7 major users listed in the proposal. These users have 13 NIH grants that will benefit from this instrument. These users also have over 60 XAS publications in the last three years using the facilities and current detector of the Resource Center. In addition, these major Husers identify 18 NIH funded collaborators (with 20 additional NIH Hgrant programs pertinent to the proposal) who will benefit from the Hacquisition of this instrument. The available beamtime for XAS on the HX9B beamline is 2-fold oversubscribed. These NIH funded users and Htheir collaborators have few alternatives for completing their experimental programs. Increasing throughput by a factor of three using the new instrument would be an extraordinary benefit to this productive and well-funded user community.
