In this thesis, a new generation of a trARPES experiment has been successfully built up from scratch combining the advantages of a ToF momentum microscope with a lab-based HHG source, delivering femtosecond EUV pulses, and a flexible pump-beamline all operating at the exceptional repetition rate of 1 MHz. The setup is benchmarked and used to investigate the non-thermal dynamics of graphene and the electromagnetic dressing of the electron energy spectrum of Au(111).
