HIPPIE is a state-of-the-art beamline for Ambient pressure X-ray photoelectron spectroscopy (APXPS). The combination of the exceptional performance of the 3 GeV ring with an innovative design of the experimental station results in a beamline that is not just outstanding in a pure electron spectroscopy context but also significantly expands the scientific issues that can be addressed. The overarching objective of the HIPPIE beamline is to address the pressure and materials gaps, that is to relax the vacuum constraints, which traditionally have limited the processes and systems possible to study, and to move from model to real – and thereby often much more complicated – materials systems

HIPPIE, along with the complimentary branch of SPECIES, make up the MAX IV APXPS group. With differing photon characteristics and sample environments, together these two beamlines allow for a diverse range of APXPS experiments.

Available forTechnique description
General UsersCatalysis Cell

- Allows APXPS of a solid-gas interface, typically up to 10 mbar. Used for catalysis and surface science experiments
- Possibility to transfer samples in a vacuum suitcase to/from the offline STM in the SPM lab at MAX IV (this option requires adding “SPM-lab” as a second beamline to your proposal)
General UsersPM-IRRAS

Allows APXPS and FTIR on the same spot. Used for catalysis and surface science experiments
General UsersLiquid/Electrochemistry Cell

Allows APXPS of a solid-liquid (dip-and-pull setup) and gas-liquid (liquid jet setup) interfaces up to 30 mbar for electrochemistry, energy, environmental, and atmospheric science experiments.
