AI Technical Summary
Existing XAFS monochromators have limitations in terms of insufficient time resolution, severe mechanical life loss, low light throughput utilization, and inability to achieve simultaneous multi-element detection, making it difficult to meet the requirements for transient in-situ characterization of multi-element coupled reaction processes.
A high-frequency fast-scan transient multi-energy spectral monochromator with circular motion is designed. It adopts multi-faceted prisms and various slotted crystals. By rotating and adjusting the pitch angle θ and included angle α of the slotted crystals, multi-energy scanning of the incident beam is achieved. Combined with a high-precision motion mechanism and a water-cooling system, stability and cooling effect are ensured.
It achieves efficient adaptation to high-power synchrotron radiation sources, improves time resolution, and has the ability to resolve multiple elements instantaneously in situ. It overcomes the limitations of traditional monochromators and provides key technical support for a new generation of X-ray absorption spectroscopy experimental stations.
