SIM - X11MA: Surfaces / Interfaces: MicroscopyThe SIM beamline produces a high flux of soft X-rays with variable polarization from an undulator source. The beamline has one permanent endstation open to user via the SLS proposals system:
The PEEM is equipped with a small preparation chamber (sputtering, heating, load-lock). In addition, a more complete preparation system is available with a load-lock, LEED and Auger, several evaporation sources, rotatable electromagnetic coil, ion etching and electron bombardment heating.
Users can apply for beamtime with the PEEM or with their own endstation (after prior consulation with the beamline scientist).
The SIM beamline is operated by the Microscopy and Magnetism Group.
