Description:
The subject of this thesis is the measurement of the energy spectrum of ultra-high energy cosmic rays from simultaneous observation of fluorescence and surface detectors of the Pierre Auger Observatory. Extending the nominal energy range of the Pierre Auger Observatory to lower energy, the hybrid energy spectrum above 10^ eV is measured. It shows a significant break of the power-law behavior at 10^ eV...
