SECOND GENERATION MULTILAYER ANALYZER ARRAY DETECTOR

本子项目是利用由NIH/NCRR资助的中心赠款提供的资源的众多研究子项目之一。子项目和研究者（PI）可能已经从另一个NIH来源获得了主要资金，因此可以在其他CRISP条目中表示。列出的机构是中心的，不一定是研究者的机构。我们之前已经构建了用于x射线荧光的多层分析仪阵列（MAAD）探测器。该检测器可以采用非常大的计数率。然而，探测器的能量分辨率与固体探测器的能量分辨率是兼容的。我们目前正在开发双多层分析仪阵列探测器（DMAAD），以大大提高能量分辨率和背景抑制率。这种探测器在很大的能量范围内是可调的。它将有一个极好的能量分辨率（2-3%的带宽），并将覆盖一个大的检测立体角与合理的吞吐量。为了实现这些目标，APS的18-ID和20-BM波束线提供的波束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.
