      abstract     = {The fundamental mechanism responsible for optically induced
                      magnetization dynamics in ferromagnetic thin films has been
                      under intense debate since almost two decades. Currently,
                      numerous competing theoretical models are in strong need for
                      a decisive experimental confirmation such as monitoring the
                      triggered changes in the spin-dependent band structure on
                      ultrashort time scales. Our approach explores the
                      possibility of observing femtosecondband structuredynamics
                      by giving access to extended parts of the Brillouin zone in
                      a simultaneously time-, energy- and spin-resolved
                      photoemissionexperiment. For this purpose, our setup uses a
                      state-of-the-art, highly efficient spin detector and
                      ultrashort, extreme ultraviolet light pulses created by
                      laser-based high-order harmonic generation. In this paper,
                      we present the setup and first spin-resolved spectra
                      obtained with our experiment within an acquisition time
                      short enough to allow pump-probe studies. Further, we
                      characterize the influence of the excitation with
                      femtosecond extreme ultraviolet pulses by comparing the
                      results with data acquired using a continuous wave light
                      source with similar photon energy. In addition, changes in
                      the spectra induced by vacuum space-charge effects due to
                      both the extreme ultraviolet probe- and near-infrared
                      pump-pulses are studied by analyzing the resulting spectral
                      distortions. The combination of energy resolution and
                      electron count rate achieved in our setup confirms its
                      suitability for spin-resolved studies of the band structure
                      on ultrashort time scales.},
