Recent Achievements and Future of Mass Measurements with Fast Radioactive Beams Available to Purchase

Fast radioactive beams offer mass measurements of exotic short‐lived nuclides. Primary beams accelerated to relativistic energies can produce in a production target a large variety of ions. GSI in Germany and NSCL at MSU in the USA are facilities that have devices and projects for mass measurement with fast radioactive beams. Two complementary methods at the storage ring at GSI are already implemented and are producing results. Two experiments that used the fast mass spectrometry of individual ions with the storage ring in isochronous mode produced new mass values of exotic neutron‐rich nuclides. A new TOF‐Bρ mass measurement method project has been started at the NSCL facility.
