Superferric Magnets for Super-FRS and Storage Rings of FAIR
IMP, Lanzhou, China
The Super Fragment Separator (Super-FRS) is conceived as a large acceptance fragment separator, with three branches serving different experimental areas, including a new storage ring complex. Rare isotopes of all elements up to uranium can be spatially separated by the Super-FRS. Unique studies with these isotopes and antiprotons will be performed in the Ring Branch, consisting mainly of a Collector Ring (CR), the New Experimental Storage Ring (NESR), and the Recycled Experimental Storage Ring (RESR). A common requirement for the magnets of these systems is a large acceptance at moderate fields, which can be fulfilled by superferric magnets with wide apertures. Similar requirements for the Super-FRS and CR magnets allow using the same magnet designs for both systems, yielding a reduction of costs and development time. Rare ions and anti-protons will be decelerated in the NESR and RESR, thus requiring pulsed magnets. This requires a coil design different from CR and Super-FRS. The cryostat design has to prevent large eddy current losses. This paper describes the status and development of the aforementioned superferric magnets. Differences and common features will be clarified. |
