The CARNAÚBA beamline is the tender-to-hard X-ray nanoprobe under construction for the new source Sirius at the Brazilian Synchrotron Light Laboratory (LNLS). The all achromatic optics relies on KB mirrors and a horizontal secondary source aperture (SSA) to reach beam size down to ∼30x30 nm2 at the sample position. To handle the power on the optical elements the choice has been to build instruments based on cryogenically cooled Si crystals. These optical elements – X-ray diagnostic, primary mirrors, secondary source aperture and monochromator – and expected performance are described here.
