Zusammenfassung:This paper reports that the countermeasures against X-ray intensity fluctuation have been developed on BL11XU at SPring-8. Observed X-ray intensity fluctuation might be caused from mechanical vibrations of monochromator crystals. So, we measured the vibrations under various conditions to identify vibration sources and took countermeasures against the mechanical vibrations. As a result, the methods successfully removed the mechanical vibrations and the X-ray intensity fluctuation was reduced to about half.
