SSUO is the organisation for all Swedish users of synchrotron radiation and free electron laser (FEL) facilities. Our primary aim is to achieve optimal conditions, including financial support, for Swedish researchers to use synchrotron radiation both nationally and internationally. To do this, SSUO will interact on the national level with funding agencies such as the Swedish Research Council Vetenskapsrådet.


SSUO is the Swedish member organization of ESUO, the European Synchrotron and Free Electron Laser User Organisation, which exists for the whole European user base of photon-driven large scale facilities. SSUO is also a sister organisation of FASM, the MAX IV Laboratory User Organisation.


We exist to promote the interests of synchrotron and FEL users in Sweden; users from all scientific disciplines are welcome. At the moment there is no formal membership procedure, but we are working on establishing one.
