The angle resolved photoelectron spectroscopy (ARPES) has emerged as a leading technique in identifying static key properties of complex systems such as adsorbed molecules, ultrathin quantum-well films or high temperature superconductors. We present an experimental setup combining the ARPES technique with a pump-probe scheme for time-resolved measurements using a 1 kHz femtosecond XUV source [1]. The performance of the system with respect to time-, energy- and momentum-resolution will be discussed on the basis of ARPES spectra recorded with ultra short photon pulses of an energy of 42 eV. Furthermore, the potential of time-resolved ARPES to study surface dynamics in future experiments is considered.
