FinEstBeAMS is a materials and atmospheric science beamline at the MAX IV 1.5 GeV storage ring. It provides ultraviolet and soft X-ray radiation with precisely controlled and widely variable parameters. The beamline has two branches: one branch is dedicated to ultra-high vacuum studies of surfaces and interfaces and the other to gas-phase experiments and photoluminescence in solids. The range of research extends from the electronic structure studies of free particles (atoms, molecules, clusters and atmospheric particles) in gas phase and on surfaces to formation analysis and nanoscale characterisation of surfaces and interfaces. The design of the beamline facilitates sample transfer between the end stations, offering synergy between gas phase and solid-state research.
An Estonian and Finnish consortium, supported by the EU through the European Regional Development Fund and the Academy of Finland, has provided funding for the construction of the beamline, instrumentation and staff.

The quest for better medical imaging at MAX IV
Advances in the world of physics often quickly lead to advances in the world of medical diagnostics. From the moment Wilhelm Röntgen discovered X-rays he was using them to look through his wife’s hand. A lot of the physics principles at the foundation of MAX IV are also at the foundation of medical imaging technologies
