  We analyze the scope of pump-probe experiments at the European XFEL involving IR/THz and x-ray pulses. Different experiments impose different requirements on the properties of the IR/THz source like wavelength range, spectral properties, intensity, pulse duration, polarization, synchronization capabilities, repetition rate, etc. Our previous analysis have shown that the most universal solution of the problem of the IR/THz radiation source is an accelerator based source. The electron accelerator is similar to that operating at the PITZ facility. It consists of an rf gun and a warm (or cold) accelerating section. Powerful, coherent radiation with prescribed temporal, spectral and polarization properties is generated in a set of radiators like undulators (using mechanism of SASE FEL for short wavelength and coherent undulator radiation for long wavelength), edge radiators, OTR foils, diffraction radiators. Location of the electron source close to the experiment would allow performing of pump-probe experiments involving also ultrashort electron pulses. In this paper we discuss problems of the integration of the accelerator based THz source into infrastructure of the European XFEL.
