The VXSF was established in 2018 as a specialist X-ray spectroscopy facility that provides an integrated capability for the characterisation of materials, processes and devices under control of environmental conditions, including in situ and operando studies.
The core of the facility is an integrated ultra-high vacuum/near ambient pressure (NAP) X-ray photoelectron spectroscopy (XPS) system, which provides the entire range of currently possible non-synchrotron XPS analysis capability for materials and devices that would otherwise be difficult to characterise in existing facilities, due to having one or more of the following characteristics:
- Vapour pressures too high for ultra-high vacuum analysis – Examples include most liquids and solutions, soft matter and formulated materials, pastes, organic and biological materials, cells, tissues, chemical reaction systems.
- Flows systems and devices
- Electrically insulating characteristics
