SIS - X09LA: Surface / Interface Spectroscopy
The Surface/Interface Spectroscopy (SIS) beamline provides a state-of-the-art experimental set-up to study the electronic band structure of novel complex materials by spin- and angle-resolved photoemission spectroscopies. The beamline operates in the energy range from 20 to 800 eV with high flux, high resolution, variable polarization, and low high-harmonic contamination.
The beamline serves two endstations:
- ULTRA (Ultra Low-Temperature high-Resolution ARPES)
for angle-resolved photoelectron spectroscopy (ARPES)
- COPHEE (Complete PHotoEmission Experiment)
for spin- and angle-resolved photoelectron spectroscopy (SARPES)
Users can apply for beamtime with the provided endstations or with their own endstation (after prior consultation with the beamline scientist).
