MAX IV Laboratory is currently operating three storage rings for the production of synchrotron radiation for both national and international researchers. In addition it is engaged in the construction of a new facility to become operational in 2015 that comprises of two storage rings (1.5 Gev and 3 Gev) and a 3 GeV Linac. The three operating storage rings are MAX I (550 MeV, established in 1986), MAX II (1.5 GeV, established in 1997) and MAX III (700 MeV, established in 2007). As a common injector for all three stoarge rings a 400 MeV linac is used. About 850 individual researchers from more than 30 countries visit the laboratory every year. The laboratory operates beamlines covering a wide spectral range from IR through UV, VUV, soft x-rays into the x-ray regime. The laboratory has a strong tradition in electron and photon spectroscopies. One example is beamline I511-1 where photoemission and photoabsorption spectroscopy can be used to study surfaces and surface adsorbates under near-ambient pressure conditions.
