Electron-electron coincidences from surfaces - The new CoESCA station at Bessy II — •Torsten Leitner^1,2, Ieva Bidermane^1,3, Ruslan Ovsyannikov^1,3, Frank O.

We introduce the new CoESCA experimental station for electron-electron coincidences from surfaces, which is open for external users at the BESSY II synchrotron facility. The station is equipped with two Angular-resolved Time-Of-Flight (ArTOF) electron spectrometers and a state-of-the art sample manipulation and preparation system. We show first results from photo electron - Auger electron coincidences from Ag and present an outlook on future research opportunities.
