The CATERETÊ group is responsible for managing and operating the CATERETÊ beamline of the synchrotron light source Sirius, at the Brazilian Synchrotron Light Laboratory (LNLS). This beamline will be optimized to perform Coherent X-ray Diffraction Imaging (CXDI), X-ray Photon Correlation Spectroscopy (XPCS) and Ultra Small Angle X-ray Scattering (USAXS). Among its applications are the investigation of the dynamics of biological phenomena and nanoscale structures in the areas of catalysts, polymers and petroleum, as well as in solving problems of the food, pharmaceutical and cosmetic industries.

The staff is responsible for assembling the instrumentation necessary for performing the experiments, for advising users in the operation of the equipment, and in the acquisition and processing of the data obtained in the beamline.

Cateretê Beamline

The CATERETÊ (Coherent And TimE REsolved ScatTEring) beamline will provide unique capabilities in biological and soft materials imaging and dynamics experiments with particular focus on the application of coherent X-ray scattering and diffraction techniques.
