摘要:

本项目探索了由阿贡国家实验室(ANL)与美国国家标准与技术研究院(NIST)合作开发的、用于共振软X射线散射(RSXS)测量的跃迁边缘传感器(TES)光谱仪的设计与研制。软X射线散射是一种在微观层面研究材料电子与磁性质的有力技术。然而,高性能软X射线光谱仪的缺乏限制了该技术的潜力。TES光谱仪因其高能量分辨率、高效率以及宽能量范围,有潜力克服这些限制。本项目旨在优化用于RSXS测量以及更广泛的先进光子源(APS)29-ID线站软X射线光谱学的TES光谱仪设计,从而增进对先进材料的理解。我们将给出仪器设计与实施的详细描述。该光谱仪由约250个高速高分辨率像素组成的大型阵列构成。这些像素的饱和能量约为1 keV,脉冲持续时间小于毫秒,能量分辨率约为1 eV。该阵列采用每通道具有MHz带宽的微波复用芯片读出,从而实现高效的数据吞吐。为便于在束线超高真空条件下对样品进行原位测量,该光谱仪与一个长约1 m的探头集成。

英文摘要:

This project explores the design and development of a transition edge sensor (TES) spectrometer for resonant soft X- ray scattering (RSXS) measurements developed in collaboration between Argonne National Laboratory (ANL) and the National Institute of Standards and Technology (NIST). Soft X-ray scattering is a powerful technique for studying the electronic and magnetic properties of materials on a microscopic level. However, the lack of high-performance soft X-ray spectrometers has limited the potential of this technique. TES spectrometers have the potential to overcome these limitations due to their high energy resolution, high efficiency, and broad energy range. This project aims to optimize the design of a TES spectrometer for RSXS measurements and more generally soft X-ray spectroscopy at the Advanced Photon Source (APS) 29-ID, leading to improved understanding of advanced materials. We will present a detailed description of the instrument design and implementation. The spectrometer consists of a large array of approximately 250 high-speed and high-resolution pixels. The pixels have saturation energies of approximately 1 keV, sub-ms pulse duration and energy resolution of approximately 1 eV. The array is read out using microwave multiplexing chips with MHz bandwidth per channel, enabling efficient data throughput. To facilitate measurement of samples in situ under ultra-high vacuum conditions at the beamline, the spectrometer is integrated with an approximately 1 m long snout.
