The Super-FRS

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.

The high-radiation load in the target area requires a dedicated design. The heavy shielded area includes the high-power production target as well as the beam-catcher stations which will remove the non-reacting primary beam. Remote handling must be applied and maintenance will take place in a Hot Cell complex which is integrated in the Super-FRS Target Building.

Specialized detector systems for full particle identification of the separated nuclides verify the separation performance and provide tagging information for the experiments on an event-by-event base.

An overview of the technical charakteristics can be found here.

Experiments for the development of Super-FRS are carried out at FRS.
