A_from free atoms to surfaces

FinEstBeaMS at the MAX IV 1.5 GeV storage ring is a materials science beamline dedicated to provide high quality radiation with precisely controlled and widely variable parameters for a broad range of materials research. Studies at FinEstBeaMS range from the electronic structure of atoms, molecules and clusters in a gas phase and on surfaces, to formation analysis and nanoscale characterisation of surface interfaces. The design aims to provide a two-branch beamline – one for ultra-high vacuum (UHV) surfaces and interface studies, and the other for high-pressure volatile materials experiments and photoluminescence studies. Furthermore, the design of the beamline facilitates sample transfers between two endstations, thereby providing a degree of synergy between the gas phase and solid state research. Funding for the basic equipment and instrumentation, materials, and staff during the construction phase was provided by an Estonian and Finnish consortium, supported by the EU through the European Regional Development Fund and the Academy of Finland.
