| Popis: | 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.
