Purpose and Goals
Soft x-rays of tuneable wavelength and variable polarisation are a tool for scientific studies with a broad range of applications, including
• The interaction of radiation with matter.
• Molecular arrangements and their electronic structure from gases to liquids.
• Transmission microscopy in aqueous environments.
• Microscopy and manipulation of magnetic nano-structure.
• Studies of electronic states in materials with strong electron interactions.
In this workshop we discuss the current science program of beamline P04 and the medium-future science program of the coming years at the PETRA III storage ring.
The discussions will also serve to sharpen the case for soft x-ray science at the new storage ring PETRA IV. The instrumentations and their upgrades are discussed from the beam delivery to the measurement stations.
The following topics will be part of the workshop:
• Excitation spectra of neutral atoms, small clusters and ions.
• Photoelectron emission characteristics of small quantum systems upon inner-shell ionising excitations.
• Chemistry of solvation at the interface between aqueous solutions and vacuum.
• Microscopy of minerals and biological samples in aqueous environments.
• Holographic imaging techniques using x-rays.
• Generation and manipulation of magnetic nano-objects using magnetic fields and optical excitation pulses.
• Effects of microscopic confinement and layering of electronic structures of solids.
• Quasiparticle excitations due to topologically stabilised interface states on the boundary of solid materials.
• Magnetic structures at ultralow temperatures and their rearrangements in phase transitions.
Abstracts and contributions are welcome to the above subject areas that represent an initial outline and are open to further suggestions.
The workshop will include a mix of solicited, contributed, and poster presentations. This meeting is also intended to inspire new projects and offer a discussion space to foster collaboration between workshop participants from the various research fields.
