ARXPS with EW4000 (CH)

EW4000, central distribution chamber and LT-STM module

At a Glance

This EW4000 XPS/UPS/ARPES analyser integration to a multi-module-system is situated at the SLS (Swizz Light Source) at the Paul-Scherrer Institute in Villingen, Switzerland.

The synchrotron end-station is connected to a central distribution chamber which allows sample transfer to/from an LT STM/AFM module and another combined analysis/preparation chamber under true UHV conditions.

The analysis/preparation chamber provides includes an R3000 XPS/UPS analyser for pre-characterization of new samples. The EW4000 with its wide-angle lens features superb angle- as well as energy-resolution used for angle resolved XPS.
