Abstract
Synchrotron scanning X-ray microscopy has been established as a mature technique, bridging the gap between conventional optical microscopy and high-resolution electron microscopy and, notably, adding advantages like large penetration in bulky samples, dose reduction and spectroscopy. The CARNAÚBA beamline at the 4th generation synchrotron source Sirius-LNLS provides an X-ray nanoprobe for simultaneous multi-analytical and coherent X-ray imaging techniques, with spectroscopic capabilities in the 2.05 to 15 keV energy range. The sample is raster-scanned through the nanoprobe to provide two-dimensional maps, which can then be combined with a rotation for computed tomography. In this contribution, some relevant scientific cases for the Day-1 experiments will be presented, along with original instrument solutions for in situ, in operando, cryogenic and in vivo sample environments.
