Abstract: Developments on high power tunable THz source forpump-probe experiments at the European XFEL are ongoing atthe Photo Injector Test facility at DESY in Zeuthen (PITZ). ALCLS-I undulator is used for proof-of-principle experiments atPITZ. Narrow-band 3 THz pulses with pulse energy of~100 microjoules were generated in a single pass using 2-3 nC17 MeV electron bunches from the high brightness photo injector.First characterization results of the THz FEL at PITZ arereported.
