The SAPUCAIA Group is responsible for the management and operation of the SAPUCAIA beamline of the synchrotron light source Sirius,  at the Brazilian Synchrotron Light Laboratory (LNLS).

The SAPUCAIA beamline will be dedicated to studies of morphology and supramolecular organization of different types of materials using the Small Angle X-ray Scattering (SAXS). The application of this technique ranges from biological studies, such as the structure of proteins and interactions of drugs with tissues, to applications in catalysis and processes of formation of nanoparticles or mesoporous materials. Due to the high flux of the  beamline and camera’s low background, time-resolved studies in all areas of research are also planned.

Sapucaia Beamline

SAPUCAIA will be a beamline dedicated to Small-Angle X-ray Scattering technique (SAXS). SAXS is a structural characterization technique used to study the morphological (shape, size, and spatial organization) and dynamical properties of nano- and micro-structured objects. It is a well-established technique, having application in a wide variety of research fields such as in physics, chemistry, biology, and engineering.
