The aim of AMADEUS is to provide unprecedented experimental information on K- absorption in light nuclear targets, to face major open problems in hadron nuclear physics in the strangeness sector, namely the nature of the λ(1405), strongly related to the possible existence of kaonic nuclear clusters, kaons and hyperon scattering cross sections on nucleons and nuclei. These issues are fundamental for a better understanding of the non-perturbative QCD in the strangeness sector. AMADEUS step 0 deals with the analysis of the 2004-2005 KLOE collected data. The interactions of the negative kaons produced by the DAφNE collider (a unique source of monochromatic low-momentum kaons) with the materials of the KLOE detector, used as active targets, provide samples of K- absorptions on H, 4He, 9Be and 12C, both at-rest and in-flight. A second step deals with the data from the implementation in the central region of the KLOE detector of a pure graphite target, providing a high statistic sample of K- 12C nuclear captures at rest. For the future a new setup, with various dedicated gaseous and solid targets, is under preparation.
