This beamline has been designed for a complete electronic structure determination using scanning-angle-resolved photoemission spectromicroscopy combined with a local structural characterization by means of Photoelectron Diffraction (PED) through its both modes, Forward scattering and Backscattering energy regimes. The central part of the project is focused on a finely tuned Fermi Surface Mapping study of crystalline complex materials with sub-micron (nano) spatial discrimination. The beamline consistently satisfies the conditions of a high-energy resolution and high-flux source of photons at the nano-size focal point provided by a Zone Plate (ZP) and order selection aperture (OSA) system. A spatial-scan sample manipulator with a resolution better than 30nm will control the temperature, angular and spatial position of the sample.
