The UUPS is a facility funded by EPSRC and aims to support materials chemical analysis for research in Northern Ireland as well as research in atmospheric pressure plasmas. Access to the facility is free and prioritised according to the strategic aims above. Please contact the PI or the UUPS Research Officer below for more details.
|The UUPS is an X-ray photoelectron spectroscopy (XPS) facility with a number of features that include ultraviolet photoelectron spectroscopy (UPS), relfective electron energy loss spectroscopy (REELS), ion scatterning spectroscopy (ISS) etc. The facility is also equipped with an additional processing chamber, the PAD, customised for atmospheric pressure plasma research. The main analysis unit provides full spatially resolved (< 15 μm) XPS chemical analysis via a monochromatic Al Kα source with variable spot size (~100-20 μm) and electron analyser with matching kinetic energy range covered by the photon source. XPS depth profiling is obtained via an angle-resolved capability (non-destructive, 1-10 nm) or via a noble gas ion cluster source (destructive, >10 nm). High resolution analysis of the electronic band structure of bulk and nanomaterials is facilitated by XPS, UPS and REELS analysis. UPS uses a discharge lamp optimized for He (I)/He(II) with a resolution of ~0.5 eV or better.Further details about the UUPS specifications are available HERE.|
