Abstract
The X-ray emission spectrometer at SPring-8 BL07LSU has recently been upgraded with advanced modifications that enable the rotation of the spectrometer with respect to the scattering angle. This major upgrade allows the scattering angle to be flexibly changed within the range of 45-135°, which considerably simplifies the measurement of angle-resolved X-ray emission spectroscopy. To accomplish the rotation system, a sophisticated sample chamber and a highly precise spectrometer rotation mechanism have been developed. The sample chamber has a specially designed combination of three rotary stages that can smoothly move the connection flange along the wide scattering angle without breaking the vacuum. In addition, the spectrometer is rotated by sliding on a flat metal surface, ensuring exceptionally high accuracy in rotation and eliminating the need for any further adjustments during rotation. A control system that integrates the sample chamber and rotation mechanism to automate the measurement of angle-resolved X-ray emission spectroscopy has also been developed. This automation substantially streamlines the process of measuring angle-resolved spectra, making it far easier than ever before. Furthermore, the upgraded X-ray emission spectrometer can now also be utilized in diffraction experiments, providing even greater versatility to our research capabilities.
在 SPring-8 BL07LSU 上通过创新的光谱仪旋转机制实现了角度分辨 X 射线发射光谱设施。
SPring-8 BL07LSU 的 X 射线发射光谱仪最近进行了先进的升级改造，使光谱仪能够相对于散射角旋转。这一重大升级允许在 45-135° 范围内灵活改变散射角，从而大大简化了角度分辨 X 射线发射光谱的测量。为了实现旋转系统，我们开发了一个精密的样品室和一个高精度的光谱仪旋转机构。样品室有一个专门设计的三个旋转台组合，可以在不破坏真空的情况下沿着宽散射角平稳地移动连接法兰。此外，光谱仪是通过在平坦的金属表面上滑动来旋转的，从而确保了极高的旋转精度，并且在旋转过程中无需再做任何调整。此外，还开发了一套控制系统，将样品室和旋转机构集成在一起，实现了角度分辨 X 射线发射光谱测量的自动化。这种自动化大大简化了角度分辨光谱的测量过程，使其比以往更加简便。此外，升级后的 X 射线发射光谱仪现在还可用于衍射实验，为我们的研究能力提供了更大的多功能性。
