The CATERETÊ Group is responsible for the management and operation of the CATERETÊ beamline of the synchrotron light source Sirius, at the Brazilian Synchrotron Light Laboratory (LNLS). The beamline is optimised to perform coherent scattering experiments. The main techniques are Coherent X-ray Diffraction Imaging (CXDI), X-ray Photon Correlation Spectroscopy (XPCS) and Ultra Small Angle X-ray Scattering (USAXS). The scientific applications cover a wide range of problems in the biology and materials science fields.

CATERETÊ group is also dedicated to the development of advanced sample environments compatible with cryo-system and high temperature reactors.
