Sirius is one of the first fourth-generation Synchrotron Light Sources to be built in the world and will have the highest brightness among the light sources in the energy range that goes from soft x-rays to hard X-rays with energies up to 20 keV.
–Access to New Science: to make the most out of the high brightness of a fourth-generation Synchrotron Light Source to explore techniques such as coherent scattering, nanofocus and inelastic scattering spectroscopy;
–Improvement to Current Science: to provide access to enhanced versions of experimental techniques currently available through the high brightness and wide spectrum provided by the Source;
–Innovation in Strategic Areas: to provide high-tech tools to solve problems in strategic areas for the Country.
– Carnauba (Coherent X-rAy NAnoprobe BeAmline) is a beamline for multiple advanced techniques using X-ray absorption, scattering and emission, and combining coherent light with nano-focusing. It is the longest of Sirius beamlines, with 145 meters distance between the light source and the sample environment. This length is required to produce a high optical demagnification and attain a focus size of about 30 nm.
– EMA (Extreme condition Methods of Analysis) beamline will be dedicated to study samples under extreme thermodynamical conditions by coupling both microfocus (1×1 µm2) and nanofocus (100×100 nm2) beamsizes to x-ray magnetic spectroscopy, x-ray diffraction and x-ray coherent imaging in multiple experimental instruments, placed along the beam path for optimization.
