Overall Introduction of the Beamline Station:
Angle-resolved photoemission spectroscopy (ARPES) stands as the sole experimental technique capable of precisely characterizing the band structure within the momentum space. Synchrotron radiation sources possess unparalleled advantages in the accurate measurement of elements, electron energy levels, orbital states, spin states, and more. ARPES based on synchrotron radiation represents one of the most critical experimental techniques for exploring the electronic structures of solid materials. It plays a pivotal role in numerous fields, including high-temperature superconductivity, graphene, and topological insulators. For instance, it has unveiled the remarkable multi-quantum-degree-of-freedom correlation effects in high-temperature superconducting materials, the non-trivial band structures in topological electronic materials, and the Dirac cone band dispersions in graphene materials.
