Synchrotron radiation facility at Lund University in Sweden
MAX IV is the world's first 4th generation synchrotron light source facility in Lund, Sweden. Its design and planning was carried out within the Swedish national laboratory, MAX-lab, which up until 2015 operated three storage rings for synchrotron radiation research: MAX I (550 MeV, opened 1986), MAX II (1.5 GeV, opened 1997) and MAX III (700 MeV, opened 2008). MAX-lab supported about 1000 users from over 30 countries annually.
