Vapor phase – gases and liquids

In order to understand the interaction of radiation with matter and the structure of solids at a microscopic level the starting point is to study single atoms and molecules. The investigation of these relatively simple systems can provide information that can be utilized to gain insight into more complex systems such as macromolecules, adsorbates, clusters, solids and their interfaces. FinEstBeAMS is dedicated for vapor phase research.

At FinEstBeAMS it is possible to investigate:

  • Free atoms, molecules and clusters
  • Atmospheric molecules and clusters
  • Metal clusters and nanoparticles
  • Industrially and biologically important molecules
  • Ionic liquids
  • Reaction chemistry and radicals
  • Fundamental molecular dynamics
  • UV and soft X-ray induced photochemistry

The main investigation methods are Photoelectron spectroscopy, Ion time-of-flight mass spectroscopy, and Photoelectron photoion coincidence spectroscopy.

Atmospheric research

FinEstBeAMS warmly welcomes the atmospheric research community. Presently, studies of gas-phase and liquid samples are possible, while a sample delivery system for aerosols and nanoparticles is under commissioning. Available instruments include a hemispherical electron energy analyzer and ion time-of-flight mass spectrometer. In addition, the gas-phase end station is highly flexible and allows the installation of users’ own sample generation systems and analysis setups, whereby they either complement or replace temporarily the end station’s standard instruments. An empty ultrahigh vacuum chamber is also available for user experiments.

Gas-phase research activities at FinEstBeAMS are part of Low-density-matter (LDM) research at MAX IV. Gas-phase users of FinEstBeAMS have a possibility to benefit from sample delivery systems and scientific equipment that are available in the LDM team and at other LDM related beamtimes.

Photoluminescence – investigations of band structure

Band structure of materials will determine its properties. In order to predict the properties of different functional materials and to develop novel devices, intensive investigation of luminescent materials is needed in order to improve our life style.

At FinEstBeAMS it is possible to investigate:

  • Time-resolved photoluminescence spectroscopy in solids
  • Pump-probe optical spectroscopy in solids
  • Radiation effects and defects in solids

The main investigation tool is IR, Vis, UV photoluminescence spectroscopy.

Solid surfaces and interfaces

The surface, the outermost layers of the solid and the interface, the boundary between the two phases or matter, are important subjects of physics and chemistry, since in many cases they determine the performance of devices. For example, a better understanding of catalysis, semiconductor electronics devices, super-capacitors, energy storage and producer devices are needed in order to improve their performance and thus our lifestyle.

At FinEstBeAMS it is possible to investigate:

  • Solid surfaces
  • Nanomaterials
  • Solid-molecule interfaces
  • Nanoscale physicochemical phenomena
  • Investigation of functional (e.g. biofunctional, photonic, and catalytic) nanostructures

The main investigation tools are Vacuum Ultraviolet, X-ray Photoelectron and X-ray Absorption Spectroscopy.
