Synchrotron radiation generated by a charged particle with relativistic speed deflected on circular paths is a well‐known physical phenomenon. However, in recent years this principle of radiation generation was further developed to generate picosecond pulses in the terahertz frequency range, thus closing a long‐lasting gap in brilliant pulsed terahertz sources. Recently, this radiation was detected in real‐time by ultra‐fast detectors connected to a high‐speed readout, thus allowing now the optimization of its generation. By that, new insights in diverse fields of physics are gained at the same time.
