The high brilliance of third-generation synchrotron sources increases the demand for faster detectors to utilize the available flux. The Maia detector is an advanced imaging scheme for energy-dispersive detection realising dwell times per image-pixel as low as 50 µs and count rates higher than 10 × 10 s. In this article the integration of such a Maia detector in the Microprobe setup of beamline P06 at the storage ring PETRA III at the Deutsches Elektronen-Synchrotron (DESY) in Hamburg, Germany, is described. The analytical performance of the complete system in terms of rate-dependent energy resolution, scanning-speed-dependent spatial resolution and lower limits of detection is characterized. The potential of the Maia-based setup is demonstrated by key applications from materials science and chemistry, as well as environmental science with geological applications and biological questions that have been investigated at the P06 beamline.
第三代同步辐射光源的高亮度增加了对更快探测器的需求，以便利用可用通量。Maia探测器是一种用于能量色散检测的先进成像方案，可实现每个图像像素低至50微秒的驻留时间和高于10×10每秒的计数率。本文描述了将这种Maia探测器集成到德国汉堡的德国电子同步加速器（DESY）的储存环PETRA III的光束线P06的微探针装置中。表征了整个系统在速率相关能量分辨率、扫描速度相关空间分辨率和检测下限方面的分析性能。基于Maia的装置的潜力通过材料科学、化学以及环境科学的关键应用得到了证明，这些应用包括在P06光束线研究的地质应用和生物学问题。
