  The Super FRS is a two-stage in flight separator to be built next to the site of GSI, Darmstadt, Germany as part of FAIR (Facility for Anti-proton and Ion Research). Its purpose is to create and separate rare isotope beams and to enable the mass measurement also for very short lived nuclei. Due to its three branches a wide variety of experiments can be carried out in frame of the NUSTAR collaboration. Due to the large acceptance needed, the magnets of the Super-FRS have to have a large aperture and therefore only a superconducting solution is feasible. A superferric design with superconducting coils was chosen in which the magnetic field is shaped by an iron yoke. For the dipoles this iron yoke is at warm and only the coils are incorporated in a cryostat. The multiplets, assemblies of quadrupoles and higher order multipole magnets, are completely immersed in a liquid Helium bath. With the exception of special branching dipoles all superconducting magnets of Super-FRS have been contracted and are being built by Elytt in Spain (dipoles) and ASG in Italy (multiplets). The cold test of all magnets will take place in a dedicated test facility at CERN. This contribution will present the status of manufacturing of dipoles and multiplets, and also gives a short overview on the test facility.

  The Super-FRS (Superconducting FRagment Separator) at FAIR is a two-stage in flight separator, which aims to produce rare isotopes of all elements up to Uranium and separate them spatially within a few hundred nanoseconds so that a study of very short lived nuclei can be performed efficiently. In total, it is required to construct 24 dipoles and 170 multipole magnets (quadrupole, sextupole, octupole and steering dipole). Due to the limit of space, the multipole magnets will be arranged as a group (2 ~ 9 magnets) in a common cryostat and they are called as a multiplet. The design challenge of the multiplet lies in a strong iron saturation of the quadrupole leading to disturb the field quality and high design pressure of the He vessel (20 bars). The first multiplet for the Super-FRS is constructed. The magnet column consisting of one quadrupole and one sextupole is cooled in a He vessel filled with up-to 800 liters of liquid He. The both magnets are superferric type and have a large warm bore radius of 190 mm. This paper presents the design overview and the manufacturing status of the first multiplet.
