An accelerator-based THz source is under development at the Photo Injector Test Facility at DESY in Zeuthen (PITZ). The PITZ accelerator consists of a photocathode RF electron gun enclosed by solenoid magnets, a booster cavity (cut disk structure, CDS) for further acceleration, and several precise instruments for electron beam diagnostics. The facility can produce high brightness electron beams with small emittance and currently plans to develop a tunable high-power THz SASE FEL source for supporting THz-pump, X-ray probe experiments at the European XFEL. An LCLS-I undulator, a magnetic chicane bunch compressor, and THz pulse diagnostics will be installed downstream the current setup of the PITZ beamline. Additionally to the SASE FEL, a possibility to generate THz undulator radiation from short electron bunches is under investigations. Numerical simulations of the superradiant THz radiation by using sub-picosecond electron bunches from the PITZ accelerator are presented and discussed in this contribution.
