MAX IV Laboratory

MAX IV is a synchrotron light source facility in Lund, Sweden, located in the Brunnshog innovation district alongside the European Spallation Source and Science Village. It uses synchrotron light to examine the chemical and physical properties of materials at the micrometer and nanometer scale and on nanosecond and picosecond timescales, with research applications spanning medicine, technology, biology, agriculture, industry and cultural heritage. MAX IV became operational in 2016 as the world's first fourth generation synchrotron light source, built around one linear accelerator with a single beamline and two storage rings carrying five and eleven beamlines respectively, where radiation striking samples at the end of each beamline is examined by diffraction, spectroscopy or imaging. About three hundred full time staff support roughly two thousand guest researchers a year, who publish about three hundred papers annually with an average impact factor near 7.5 and pay no fee for their beamtime, an arrangement meant to encourage applications.
