We are developing an imaging capability (“Hyperspectral X-ray Imaging”) for mapping chemical information (molecular formula, phase, oxidation state, hydration) that is based on ultra-high-resolution X-ray emission spectroscopy with large transition-edge sensor microcalorimeter arrays in the scanning electron microscope. By combining microcalorimeter arrays with hundreds of pixels, high-bandwidth microwave frequency-division multiplexing, and fast digital electronics for near real-time data processing, our goal is to enable measurements using laboratory-scale instrumentation rather than synchrotron beamlines. Our application focus here is on mapping the chemical form of uranium compounds on the nanoscale. We will present our approach to developing the Hyperspectral X-ray Imaging capability, progress toward a 128-pixel microwave multiplexed X-ray fluorescence instrument at LANL, and the path to high-throughput nanoscale chemical mapping.

使用 TES 探测器进行高光谱 X 射线成像，用于纳米级化学形态映射

我们正在开发基于超高分辨率 X 射线发射光谱和大型过渡边缘传感器的成像能力（“高光谱 X 射线成像”），用于绘制化学信息（分子式、相、氧化态、水合）扫描电子显微镜中的微量热仪阵列。通过将微量热仪阵列与数百个像素、高带宽微波频分复用和用于近实时数据处理的快速数字电子设备相结合，我们的目标是使用实验室规模的仪器而不是同步加速器光束线进行测量。我们的应用重点是在纳米尺度上绘制铀化合物的化学形式。我们将介绍我们开发高光谱 X 射线成像能力的方法，
