The MAX IV Laboratory in Lund, Sweden, is a national research laboratory comprising of MAX-lab and the MAX IV project. The MAX IV project opens new possibilities for cutting-edge research within broad areas of science, for example materials science, structure biology and nano technology. MAX IV will be the next generation synchrotron light facility and will replace the existing laboratory, i.e. the storage rings MAX I, II and III. The MAX IV Laboratory has developed out of the accelerator research that has been executed at the Lund University since the 1960’s; Lund University in Sweden is the host University for the Facility. The laboratory is a highly international forum. Nearly half of the scientists working at the laboratory are from foreign countries. MAX-lab supports three distinct research areas: Accelerator Physics, research based on the use of Synchrotron Radiation and Nuclear Physics using energetic electrons. Time at the facility is shared between groups working within these three fields. The accelerators at MAX-lab consist of three electron storage rings (MAX I, MAX II and MAX III) and one electron pre-accelerator (MAX injector). All three storage rings produce synchrotron light used for experiments and measurements in a wide range of disciplines and technologies. The MAX I ring is also used as an electrons source for experiments in nuclear physics. MAX IV will be the next generation synchrotron radiation facility in Sweden. It will replace the existing laboratory consisting of the MAX I, II and III storage rings. The main sources at MAX IV are two storage rings (1.5 GeV and 3 GeV) with state-of-the-art low emittance for the production of soft and hard x-rays. The linac injector will provide short pulses to a short pulse facility. This solution allows the production of synchrotron radiation with optimal characteristics in a wide energy region, fulfilling the needs of most diverse research areas. The MAX IV design also includes an option for a Free Electron Laser as a second development stage of the facility
