The European XFEL produces up to 20 GeV electron bunches with a repetition of up to 27 kHz to ultimately provide a large range of coherent X-rays to users with individual pulse energies on the order of 1 mJ. We discuss the development of a new experimental program, Superradiant THz radiation at the European XFEL (STERN), to produce large THz fields by passing the electron beam through Cherenkov waveguides including dielectric, corrugated, bimetallic waveguides, or crystal fibers. We discuss recent simulation and experimental results based on 3D printing these complex structures. Finally we discuss their application in our proposed novel laser-based accelerators and diagnostics, and also to provide a pump-probe platform for users at the XFEL.
