The FlexPES (Flexible PhotoElectron Spectroscopy) beamline caters for the experimental needs of both Surface/Material Science and Low Density Matter user communities offering the possibility to perform a variety of photoemission and soft X-ray absorption experiments in the photon energy range 40 – 1500 eV. The two-branch configuration with double-striped toroidal refocusing mirrors ensures maximum flexibility – up to four endstations can be accommodated on the two branches of the beamline simultaneously, and each of these endstations can avail of different focusing conditions. The end stations offer a diverse range of experimental techniques, detectors and sample handling facilities and can be used with a variety of sample delivery systems.

MAX IV Highlights 2019
2019 was a landmark year for MAX IV Laboratory. Continuing the long-standing tradition of delivering innovative technical instruments and capabilities for x-ray science to the research community since MAX-lab was inaugurated in 1987, MAX IV broke new ground by opening five new beamlines to users, and bringing three more into the commissioning phase for
