Core advantage:
1.Highest luminous flux products
The photon flux is higher than 1,000,000 photons/SEC /eV, and the spectral acquisition efficiency is several times that of other products; Get the same data quality as synchrotron radiation.
2.Excellent stability
The monochromatic light intensity stability of the light source is better than 0.1%, and the repeated acquisition energy drift is < 50 meV.
3.1% detection limit
High luminous flux, excellent optical path optimization, and excellent light source stability ensure high-quality EXAFS data with measured element content >1%.
