Overview
The ultra-high luminous flux X-ray absorption fine structure spectrometer adopts a unique Johann type Roland circle monochromator design, which does not require a synchrotron radiation source. The X-rays emitted from the point light source satisfy the Bragg equation and undergo diffraction to re converge at the detector of the Roland circle. By changing the Bragg angle, monochromatic light of different energies can be obtained, thus achieving high-quality XAFS testing in conventional laboratories.

Ultra high luminous flux X-ray absorption fine structure spectrometerPrinciple
X-ray Absorption Fine Structure (XAFS), also known as X-ray Absorption Spectroscopy (XAS), is a powerful tool for studying the local atomic or electronic structure of materials based on synchrotron radiation sources. It is widely used in fields such as catalysis, energy, and nanotechnology.
RapidXAFS adopts a unique Johann type Roland circle monochromator design, which does not require a synchrotron radiation light source. The X-rays emitted from the point light source satisfy the Bragg equation and undergo diffraction to re converge at the detector of the Roland circle. By changing the Bragg angle, monochromatic light of different energies is obtained, thus achieving high-quality XAFS testing in conventional laboratories.
XAFS spectrum:
X-ray Absorption Near Edge Structure (XANES)
Extended X-ray Absorption Fine Structure (EXAFS)
EXAFS
The energy range is approximately 50eV to 1000eV after the absorption edge, which is the result of the single electron single scattering effect of the inner layer photoelectrons excited by X-rays between the surrounding atoms and the absorbing atoms.
XANES
The range from about 10 eV before the absorption edge to about 50 eV after the absorption edge is mainly due to the single electron multiple scattering effect of the inner shell photoelectrons excited by X-rays between the surrounding atoms and the absorbing atoms.
