The KEK Wako Nuclear Science Center in collaboration with the RIKEN SLOWRI group presently operates three high-performance multi-reflection time-of-flight (MRTOF) mass spectrographs within the RIKEN accelerator complex – one for superheavy elements, one for in-flight fission and fragmentation products, and one for multi-nucleon transfer products – with more planned for the near future. With typical mass resolving power approaching m/Δ m=106, we are able to achieve relative mass precision δ m/m∼10−7 with 100 detected ions; in many cases isomeric states can be resolved. By embedding silicon detectors within the time-of-flight detector, we have initiated a new field of decay-correlated mass spectroscopy which greatly enhances the capabilities of the MRTOF. The results of recent measurement campaigns and plans for future MRTOF-based studies will be presented.
