Status of the WERA Soft X-Ray Beamline at ANKA — •Eric Pellegrin, Peter Nagel, Bernd Scheerer, and Stefan Schuppler — Forschungszentrum Karlsruhe, IFP, Postfach 3640, 76021 Karlsruhe, Germany

After its commissioning in early 2005, the WERA beamline at the 2.5 GeV ANKA synchrotron radiation facility within the Forschungszentrum Karlsruhe is to be used for classical as well as for advanced electron spectroscopy in the photon energy range between 80 and 1400 eV (with a later extension down to about 15 eV photon energy). The main objective of WERA is to provide the user with most of the presently available electron spectroscopy tools in situ in order to allow a complete characterization of the electronic as well as the magnetic structure of the sample under investigation. Thus, versatility (instead of specialization) is the primary goal for WERA.

The following experimental stations will be available (incl. an in situ sample transfer between the individual experimental setups) together with the corresponding sample preparation chambers:

-photoemission electron microscopy

-photoemission spectroscopy, resonant photoemission spectroscopy, near-edge x-ray absorption spectroscopy

-soft x-ray magnetic circular dichroism (planned)

-pulsed laser deposition of epitaxial thin film samples

The technical specifications, the status and the future developments of the WERA soft x-ray beamline project will be presented.
