The bulk properties of materials and deeply buried interfaces are of crucial importance in the understanding of different processes that take place in solids. A non-destructive experimental technique that gives access to these electronic properties is hard x-ray photoemission spectroscopy. Combining a bending magnet source and a new generation electron spectrometer optimized for high kinetic energy electrons, the HIgh Kinetic Electron (HIKE) Spectroscopy facility at BESSY in Berlin has recently become operative at the KMC-1 beam line. The first results show a very good performance. Electron spectra have been achieved using 2 keV up to 12 keV excitation energy. Using back scattering conditions in the monochromator, very high resolution has been achieved around 2 keV, 6 keV and 8 keV. In this conference contribution we will discuss this non-destructive experimental technique and illustrate its abilities through the recently obtained results.
