在SPring-8的波荡器光束线（BL 11 XU）上成功地产生了具有15.4 neV窄带宽的超高单色14.4 keV X射线，计数率高达12，000计数/s。它是通过结合来自第三代同步辐射设施SPring-8的强X射线和在Néel温度下非常高质量的57 FeBO 3完美单晶的纯核布拉格散射来实现的。本文详细介绍了同步辐射穆斯堡尔谱的光束特性和一些性能测试实验，包括金刚石压砧室的高压实验。
Ultrahigh monochromatic 14.4 keV X-rays with a narrow bandwidth of 15.4 neV were generated successfully with a high counting rate of 12,000 counts/s at the undulator beamline (BL11XU) of SPring-8. It was achieved by combining an intense X-ray from the third generation synchrotron radiation facility SPring-8 and pure nuclear Bragg scattering of a very high-quality 57FeBO3 perfect single crystal at the Néel temperature. We describe the detailed study of the beam characteristics and some performance test experiments of energy-domain synchrotron radiation Mössbauer spectroscopy, including a high-pressure experiment using a diamond anvil cel.
