  Once every decade or two, the Office of Nuclear Physics in the U.S. Department of Energy Office of Science has embarked on building a new accelerator-based user facility to enable nuclear scientists to make discoveries. Following construction starts for CEBAF in the 1980’s and for RHIC in the 1990’s, the Facility for Rare Isotope Beams (FRIB) project started in 2009 with the goal to build the most powerful superconducting heavy-ion linear accelerator. FRIB construction at Michigan State University is now 96% complete, the superconducing linac has been commissioned. FRIB is being managed to early completion in 2021 with user operation starting in early 2022. I will give an overview of the FRIB science and construction progress accomplished by a committed team delivering FRIB for a community of 1,400 scientists.

The recent development of radioactive beam facilities has significantly expanded the capabilities for investigating the structure of the atomic nucleus and the nuclear interaction. For instance, the HIE-ISOLDE facility at CERN delivers presently the largest range of low-energy radioactive beam available worldwide. This energy range is ideal for the study of nuclear structure, low-energy dynamics and astrophysics by using nucleon transfer, Coulomb excitation and deep inelastic reactions. All these studies require an efficient and high-resolution recoil separator for the clear identification of medium and large mass reaction fragments. To meet these needs, we propose a versatile recoil separator for radioisotopes based on a compact storage ring, the Isolde Superconducting Recoil Separator (ISRS) formed of superconducting combined-function nested magnets with both, bending and focusing/defocusing functions. The ISRS is designed to operate in high momentum acceptance and isochronous modes. In this paper, we present the optics design and detailed beam dynamics studies for the performance characterisation.
