FLUTE is a test facility for a compact accelerator-based THz source in the final design phase at the Karlsruhe Institute of Technology (KIT) in cooperation with Paul Scherrer Institute (PSI), Switzerland. The design is based on a 7 MeV photo injector, an S-band linac with a maximum energy of 50 MeV and a bunch compressor. The machine will be operated in a wide range of bunch charges, from 10 pC up to 3 nC. The final bunch length after the compressor is dominated by space charge effect in the photo injector and the coherent synchrotron radiation (CSR) in the compressor. This paper gives an overview over the status of the project and presents results of simulations for the different operating regimes. In addition, THz spectra generated by different processes (CSR, coherent transition radiation and coherent edge radiation) for different, charge dependent, bunch shapes will be discussed.
