The Superconducting FRagment Separator (Super-FRS) is the central device of the NUSTAR collaboration. Rare isotopes of all elements up to uranium will be produced at relativistic energies and spatially separated within a few hundred nanoseconds, enabling the study of very short-lived nuclei.

The Super-FRS is a two-stage fragment separator consisting of a Pre-Separator and a Main-Separator. Both separator stages will apply the Bρ-ΔE-Bρ method which combines a magnetic rigidity (Bρ) analysis in front and behind a shaped degrader (ΔE) system. The Main-Separator will serve three experimental branches i.e. the Ring Branch (RB), the High-Energy Branch (HEB), and the Low-Energy Branch (LEB) including a dedicated Magnetic Spectrometer/Energy Buncher stage. The Super-FRS is characterized by a large phase-space acceptance employing large-aperture superconducting magnets.
