The design of a new beamline dedicated to X-ray Absorption Spectroscopy (XAS) at the French synchrotron radiation laboratory SOLEIL is under development. This beamline dedicated to large and varied scientific communities from physics to chemistry and biology will be characterised by a lot of techniques combined to XAS, such as X-ray Diffraction, Differential Scanning Calorimetry, Raman Spectroscopy and UV-Visible Spectroscopy. The design of the SAMBA optics will be optimised in order to be very versatile, to cover the 4–40 keV energy range with a high photon flux and a good energy resolution. Measurements of the absorption coefficients will be done either in the step by step mode or in a quick mode. The beamline should be in operation in 2006. This paper summarizes its technical characteristics and calculated performances. Typically the performance would be at 10 keV around 10 12 ph/s in a 200 × 200 μm 2 beam spot.
