Our tr-ARPES endstation is connected to laser sources allowing 6.2 eV, 10.8 eV and HHG probe energies. All setups allow for variable pump-energies. Furthermore we can offer static two-photon-photoemission measurements with variable photon energy.

The endstation is equiped with a six-axis cryo-manipulator allowing for measurements at temperatures down to 40 K and a preparation chamber allowing for sample cleaving, sputtering and annealing and the deposition of inorganic or organic materials using an evaporator mountable on a CF40 port. Crystal structure and orientation can be monitored by LEED. Up to three samples can be stored in a fast entry chamber attached to the endstation.
