| مستخلص: |
Here, a recently commissioned five‐analyzer Johann spectrometer at the Inner Shell Spectroscopy beamline (8‐ID) at the National Synchrotron Light Source II (NSLS‐II) is presented. Designed for hard X‐ray photon‐in/photon‐out spectroscopy, the spectrometer achieves a resolution in the 0.5–2 eV range, depending on the element and/or emission line, providing detailed insights into the local electronic and geometric structure of materials. It serves a diverse user community, including fields such as physical, chemical, biological, environmental and materials sciences. This article details the mechanical design, alignment procedures and data‐acquisition scheme of the spectrometer, with a particular focus on the continuous asynchronous data‐acquisition approach that significantly enhances experimental efficiency.
