The QUATI (Quick X-Ray Absorption Spectroscopy for Time and space resolved experiments) beamline is dedicated to high-quality X-ray absorption spectroscopy experiments (XAS) with temporal and spatial resolutions. 

XANES (X-Ray Absorption Near Edge Structure) and EXAFS (Extended X-Ray Absorption Fine Structure) spectra will be available between 4.5 to 35 keV (covering K edges from Titanium to Xenon and the other elements with L edges).  

The high brilliance from the fourth-generation synchrotron ring SIRIUS combined with the beamline design, will allow for time-resolved measurements down to sub-second time resolution to be performed.  

The beam size will be variable from 15 x 10 μm2 to 5 x 0,6 mm2. Heterogeneous and sensitive materials will largely benefit from the size flexibility. 

Besides, with the high flux achieved in this beamline, it will be possible to study the structure of materials at high temperatures under gas flow or pressure under in situ / operando conditions, benefiting areas such as catalysis, materials science, nanotechnology, environmental and life sciences… 

Several sample environments, such as oven (with powdered or pelletised samples), electrochemical cell, cryostat and multiple ex situ sample holders will be available. The beamline can also house sample holders brought by users. 

Furthermore, the Quati beamline intends to combine X-ray techniques with other techniques to get complementary information in a single experiment. At the early stage of the beamline, mass spectrometry and Raman spectroscopy will be available. Other techniques will be implemented such as hyperspectral imaging, X-ray diffraction, X-ray emission spectroscopy and Infrared spectrometry.
