User operations have just started at WERA, IFP’s new beamline for soft x-ray spectroscopy
and microscopy in the photon energy range 90 - 1500 eV at the ANKA synchrotron
radiation facility. Emphasizing versatility, WERA facilitates combinatory
studies of electronic and magnetic structure, in particular of strongly correlated, thinfilm,
and nanoscale materials. Available methods include photoemission (PES), x-ray
absorption (NEXAFS), as well as photoemission electron microscopy (PEEM). The
experimental chambers are interconnected in UHV and accessible from various sample
preparation chambers, including pulsed-laser deposition (PLD) of epitaxial thin films.
Further endstations such as for magnetic dichroism (SXMCD) are planned as part of
a long-term cooperation with outside user groups. Salient features of beamline and
endstation layout, performance, and first experimental results will be presented.
