X-ray Photoelectron Spectroscopy (XPS) setup and Ultra-High Vacuum (UHV) Linear Transfer System (LTS)

DTU will like to purchase an X-ray Photoelectron Spectroscopy (XPS) setup and an Ultra-High Vacuum (UHV) Linear Transfer System (LTS) that connects the XPS system with other planned setups (5 in total including the XPS system in this tender). The setup will be used by academic researchers investigating catalysts. The XPS system must be able to perform: • High-resolution XPS using monochromized Al K-alpha photons. • Angle resolved XPS for non-destructive depth profiling. • Low energy ion scattering spectroscopy (ISS) using helium ions and heavier ions such as neon, argon or xenon. • Ultraviolet Photoelectron Spectroscopy using a helium UV source. • Sputter cleaning of substrates and destructive depth profiling using an Argon ion gun. • Measurements on samples transferred on SHOM flag style sampleholders and on larger samples up to 2.5 cm. The LTS will facilitate transfer of samples mounted on SHOM flag style sampleholders under UHV conditions to prevent air exposure when samples are being transferred between different setups. Through the combined purchase of the XPS and LTS system, we are looking for a solution that will enable a robust transfer of samples under UHV conditions and further establish a working solution for connecting future setups to the LTS. Please see more about the purchase in Appendix 1 – Requirement specification.
