SECOND GENERATION MULTILAYER ANALYZER ARRAY DETECTOR

该子项目是利用NIH/NCRR资助的中心赠款提供的资源的许多研究子项目之一。子项目和研究者（PI）可能从另一个NIH来源获得了主要资金，因此可以在其他CRISP条目中表示。所列机构为中心机构，不一定是研究者机构。我们以前已经构建了多层分析仪阵列（MAAD）检测器的X射线荧光。该探测器可以获得很大的计数率。然而，探测器的能量分辨率与固态探测器的能量分辨率兼容。我们现在正在开发双多层膜分析器阵列探测器（DMAAD），以大大提高能量分辨率和背景抑制率。探测器将在大能量区域内可调谐。它将具有极好的能量分辨率（2-3%带宽），并将以合理的吞吐量覆盖大的检测立体角。为了实现这些目标，APS的18-ID和20-BM光束线提供的束流时间对于表征和调试目的至关重要。

This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. We have previously constructed multiplayer analyzer array (MAAD) detectors for x-ray fluorescence. The detector can take very large count rate. However, the energy resolution of the detector is compatible to that of the solid-state detectors. We are now developing dual multilayer analyzer array detectors (DMAAD) to largely improve the energy resolution and background rejection rate. The detector will be tunable in a large energy region. It will have a superb energy resolution (2-3% bandwidth), and will cover a large detection solid angle with reasonable throughput. To achieve these goals, the beamtime provided by 18-ID and 20-BM beamlines of the APS is essential for characterization and commissioning purposes.
