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.

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.
