SIS - X09LA: Surface / Interface: Spectroscopy

The Surface and 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 photoelectron spectroscopies. The beamline has been designed for the energy range from 10 to 800 eV with high flux, high resolution, variable polarization, and low high-harmonic contamination.

The beamline serves two endstations:

• High-resolution photoemission spectroscopy (HRPES)
  for angle-resolved photoelectron spectroscopy (ARPES)
• COPHEE
  for spin- and angle-resolved photoelectron spectroscopy (SARPES)

Users can apply for beamtime with the provided endstations or with their own endstation (after prior consulation with the beamline scientist).
