%X The Photoinjector test facility at DESY in Zeuthen develops and characterizes the electron guns for FLASH and Eu-XFEL. It consists of a normal-conducting L-band RF gun cavity with a Cs2Te photocathode, which can produce beam charge up to several nC. The electron bunches can gain an energy up to  6.5 MeV after the gun and then further acceleration, up to  22 MeV, is possible by a booster cavity. The pulse train structure is identical to the one at Eu-XFEL. Considering all these features, the development of a prototype for an accelerator-based THz source was carried out at PITZ.The ideal THz source required for the pump-probe experiments at the Eu-XFEL should meet the following requirements: tunable frequency (0.1-20 THz), high pulse energy (μJ to mJ; depending upon frequency), narrow bandwidth (<1-10
