The beamline is based on a Plane Grating Monochromator (PGM); it covers wide and continuous photon energy range and is characterised by moderate flux. It ends with a fixed experimental station RGL-PES that offers a multi-technique approach for the investigation of the electronic, chemical and structural properties of materials: X-ray photoemission spectroscopy and X-ray absorption in all possible modes (fluorescence yield, total and partial electron yields).

The operation of the Russian-German Joint Laboratory at BESSY II is suspended for an undetermined period of time due to the Russian Federation's war of aggression against Ukraine. We condemn the serious breach of international law. We are concerned for all inhabitants of Ukraine and for the researchers and students affected by the war. We remain in solidarity with them.
