HIPPIE is a state-of-the-art beamline for high pressure X-ray photoelectron spectroscopy (HP-XPS). The combination of the exceptional performance of the 3 GeV ring with an innovative design of the experimental station results in a beamline which is outstanding not just in a pure electron spectroscopy context, but which also significantly expands the scientific issues that can be addressed. Thus HIPPIE will serve a much wider user community than the traditional electron spectroscopy one. 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 systems to real - and thereby often much more complicated - materials systems.
An HP-XPS end station will permit XPS and X-ray absorption spectroscopy (XAS) experiments in situ at pressures up to 25 mbar as well as under ultrahigh vacuum (UHV) conditions. The photon energy range is 263 to 2000 eV with variable polarization and very high flux and resolution. The high photon flux at higher photon energies makes it possible to study not only the core levels of the low-Z elements with high resolution, but in particular also the L-shell levels of the important late 3d transition metal elements and Zn, Ga, and As. This implies that excellent opportunities emergy for the study of samples from e.g. catalysis, corrosion, and semiconductor science. The variable polarization opens new possibilities for studies of magnetic and chiral effects in the presence of gases/liquids.
At the HIPPIE beamline research in physics, chemistry, and other sciences will be conducted. The main areas are surface science, catalysis, corrosion, semiconductor research, and materials science.
