Phys. Rev. Lett. 68, 3412–3415 (1992)First storage and cooling of secondary heavy-ion beams at relativistic energiesReceived 23 March 1992; published in the issue dated 8 June 1992 Secondary beams of radioactive heavy ions have been stored and cooled in a storage ring for the first time. Relativistic beams of bare 19Ne and 18F ions were produced by fragmentation of 310 MeV/nucleon 20Ne at the heavy-ion synchrotron at GSI. They were separated in flight with the high-resolution forward spectrometer and injected into the storage-cooler ring. The feasibilities of in-flight lifetime and direct mass measurements for radioactive beams are demonstrated. © 1992 The American Physical Society URL:
