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 for||Technique description|

|General Users||Liquid/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.
Two-dimensional materials offer versatile corrosion protection
Illustration by: Giulio D’Acunto, Lund University Two-dimensional materials can be used as a coating to protect copper from corrosion. A recent study conducted at beamline HIPPIE shows that the onset of corrosion can be delayed from room temperature up to more than 120 degrees centigrade using graphene or hexagonal boron nitride.
