ABSTRACT

BL28XU was built as the advanced analysis beamline for batteries by Kyoto university, which was the center of “Research & Development Initiative for Scientific Innovation of New Generation Batteries” (RISING, FY2009 – FY2015) project by New Energy and Industrial Technology Development Organization (NEDO).
Spatially and time resolved in situ X-ray diffraction (XRD) and X-ray absorption spectroscopy (XAS) have been employed at BL28XU for battery reaction analysis by RISING and its successive projects, RISING2 (FY2016 – FY2020) and RISING3 (FY2021 – FY2025).

AREA OF RESEARCH

• Rechargeable batteries

KEYWORD

• In situ, time resolved, microbeam
• XRD, XAFS, HAXPES

SOURCE AND OPTICS

• Light Source:
  • Tapered vacuum undulator
• Optics:
  • 1st Mirror (M1), 2nd Mirror (M2), compact monochromator, 3rd Mirror (M3), 4th mirror (M4)
  • M1 and compact monochromators are cooled by liquid nitrogen.
  • M2, M3, M4 are cooled by water.
  • All mirrors are coated with Pt and Rh.
  • The beam is focused horizontally by M1 and M2, vertically by M3 and M4 which reject higher harmonics.
  • Two compact monochromators (Si(111) and Si(220)) are installed, which are driven by a servo motor coupled with a rotary feedthrough using magnetic fluid. The available energy range is 4 – 46 keV.
  • Pinkbeam (quasi-monochromatic beam without the monochromator) is also available. The energy band of the beam can be widen by tapering the undulator gap.
