Cover Story: Research on radioactive ion beams produced through in-flight separation of relativistic beams has contributed to nuclear physics, nuclear astrophysics, atomic physics, and other fields. Central to these advancements are improved production, separation, and identification methods, which are employed with systems such as the FRS Ion Catcher at GSI/FAIR. The system facilitates high-precision experiments by efficiently stopping and extracting exotic nuclei as ions and making these available at thermal energies. High-energy synchrotron beams enable unique experimental techniques such as multi-step reactions, mean range bunching, and optimized stopping, as well as novel measurement methods for observables such as beta-delayed neutron emission probabilities. The future of the Super-FRS at FAIR promises to extend research to even more exotic nuclei and new applications. View this paper
