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.

Techniques (as available by Q1 2020)

Available forTechnique/facility description
General UsersBeamline: Linear horizontally polarized light from LPU, with energy range 40-1500 eV. Spot on sample both defocused (0.5-1.5 mm) and focused (from 50x15 um to 150x40 um in different end stations).
General UsersSurface- and Material Science (SMS) branch: High-resolution photoelectron spectroscopy (PES) on solid samples using SES-2002 analyzer and 4-axis manipulator; X-ray absorption spectroscopy (XAS or NEXAFS) using total and partial electron yield.
General UsersLow Density Matter (LDM) branch: High-resolution PES on LDM samples using R4000 analyzer with the following sample delivery systems (samples must be approved by chemical safety group):
- Liquid jet setup for e.g. aqueous solutions
- Molecular jet source (continuous beam) for experiments on cold beams of atomic and molecular gases
- Gas cell for PES experiments on atomic and molecular gases

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
