THz undulator beamline

The THz undulator beamline has been designed to provide coherent femtosecond (fs) – picosecond (ps) THz pulses for novel pump-and-probe experiments with the fs VUV pulses from FLASH. The THz pulses are generated by a purpose built undulator implemented in series to the VUV undulators. The design of the beamline allows to overlap VUV pulse and the THz pulse generated by the same electron bunch at the end of BL3. The pulses should therefore be naturally synchronized. The expected pulse energies lie within the microjoule regime. First light has been delivered into the experimental hall in November 2007. Commissioning and test of the THz beamline has since been ongoing. For further information look into the following references:
