Synchotron XPS has numerous benefits and advantages over lab based sources, the high photon flux permits superior analysis of adsorbates and trace elements, the tunable energy provides a method for the study of buried layers or density of states and dedicated NAP-XPS systems provide experimental stations to probe samples under simulated operating conditions.
Below is a list of the numerous XPS beamlines around Europe and beyond. Whilst not an exhaustive list, it may prove a useful resource for researchers looking for XPS beamlines.

High flux and fast analysis times permit analysis of changing states in real time. The use of gas dosing allows for model studies of adsorbates onto single crystals, perfect for those in the field of catalysis to study reaction pathways.
Spain, ALBA
Contact: Virginia Pérez Dieste (NAPP) / Michael Foerster (PEEM)
Techniques: XPS (100 – 2000 eV), NAP-XPS, PEEM, NEXAFS (NAPP), X-ray Absorption Spectroscopy (XAS) (NAPP), Heating and cooling (100-1500K on the PEEM endstation, -23 to 1000K on the NAPP endstation), LEED (both endstations), Mass spec (NAPP)
This beamline has 2 endstations, one dedicated to PEEM and one to NAP-XPS. Heating by infrared and cooling by Peltier element results in a system quite suitable for single crystal work and well as ‘real’ samples. Gas dosing system is automated and allows up to three different gases to be equipped at one time.
