The Photo Injector Test facility at DESY, Zeuthen site (PITZ), develops high brightness electron sources for modern linac-based Free Electron Lasers (FELs). The PITZ accelerator can also be considered as a suitable machine for the development of an IR/THz source prototype for pump-probe experiments at the European XFEL. Interesting options for the IR/THz generation with PITZ are to generate the radiation by means of a Coherent Transition Radiation (CTR) and a Coherent Diffraction Radiation (CDR). Experimental optimizations of electron beams for such means were done with two types of longitudinal profiles; short Gaussian and comb-like profiles. In this contribution, results of the optimizations are presented and discussed together with corresponding calculations of the CTR and CDR. Progress on the design and installation of a CTR/CDR station is also reported.
