– IGNIS (Ion-Gas-Neutral Interactions with Surfaces) In-situ Surface Science Facility

With UIUC Frame 3

The IGNIS facility is a state-of-the art in-situ experimental surface science facility that is capable of surface characterization of materials under extreme conditions.  The acronym “ignis” means “fire” in latin and encompasses the ability to expose surfaces to a collection of energetic particles under high-pressure and high-temperature environmental conditions during surface analysis measurements.  This unique facility allows x-ray photoelectron spectroscopy, ion-scattering spectroscopy, and Raman spectroscopy in a single chamber during the following conditions: High-intensity plasma irradiation using a hollow-cathode plasma source, neutral atom irradiation from a broad beam source with a neutralizer, photon irradiation with a UV source or laser, and electron irradiation using an e-beam source.  The charged particle spectroscopy will be done with the Specs PHOIBOS 150 NAP hemispherical analyzer.

– MAPP (Materials Analysis Particle Probe)


MAPP is an in-situ characterization device, designed to be attached to fusion reactors, expose an ensemble of samples and characterized them in a shot to shot basis. MAPP is equipped with a set of diagnostics that allow us to register chemical changes in our samples after their interaction with fusion plasmas. MAPP’s capabilities include X-ray Photoelectron Spectroscopy (XPS), Thermal Desorption Spectroscopy (TDS), Ion Scattering Spectroscopy (ISS) and Direct Recoil Spectroscopy (DRS).
