CARNAúBA (Coherent X-Ray Nanoprobe Beamline) is an X-ray beamline under construction for the SIRIUS lightsource at LNLS (Brazilian Synchrotron Light Laboratory). The aim of the beamline is to provide multi-analytical andcoherent X-ray imaging techniques based on achromatic optics in the energy range between 2 and 15 keV. Computedtomography will extend these techniques into three dimensions. Two end-stations are under development: an all-invacuumnanoprobe (SAPOTI) and a sub-microprobe (TARUM?), with a more flexible sample environment and muchlarger working distance. TARUM? will cover a large variety of scientific areas, from environmental, geophysical,agricultural and biological research to energy and more condensed matter related areas. Its design characteristics, with itsmechanical design heavily based on precision engineering concepts and predictive modeling, are presented here, as wellas some prospects on in situ, in operando and cryogenic sample environment experiments.
