The electron linear accelerators driving modern X‐ray free‐electron lasers can emit intense, tunable, quasi‐monochromatic terahertz (THz) transients with peak electric fields of V Å −1 and peak magnetic fields in excess of 10 T when a purpose‐built, compact, superconducting THz undulator is implemented. New research avenues such as X‐ray movies of THz‐driven mode‐selective chemistry come into reach by making dual use of the ultra‐short GeV electron bunches, possible by a rather minor extension of the infrastructure.
