Description

CASSIOPEE : Combined Angle- and Spin-resolved SpectroscopIes Of PhotoEmitted Electrons

The CASSIOPEE beamline is dedicated to photoemission experiments in the 8 eV -
1500 eV photon energy range. The beamline uses two undulators, and the main
optical elements are the entrance optics and the monochromator. After the
monochromator, the beamline is divided into two branches, supplying photons to
two endstations (Spin-resolved Photoemission, and High Resolution Angle-resolved
Photoemission), both connected to a Molecular Beam Epitaxy chamber.
