DRAFT 2.4.2.2.1 Radiation resistant quadrupole magnets Like the radiation resistant dipole magnets also the radiation resistant quadrupole magnets are designed as normal conducting magnets using Metal oxide Insulation Cables (MIC). Two different types of radiation resistant quadrupoles are necessary for the Pre-Separator. The first one has a pole tip radius of 100 mm providing a useful aperture of ± 90 mm. The second one has a pole tip radius of 210 mm providing a useful aperture of ± 190 mm. The design parameters for the quadrupoles can be found in Table 2.4.14 and section 2.4.2.8, respectively. Both quadrupole magnets must provide very high pole tip field for beams with a rigidity of up to 20 Tm. Saturation effects of the yoke become significant, which is partly compensated by introducing air slots in the pole. These slots are easily implemented from mechanical point of view, since laminated iron sheets are used. These slots imitate the saturation of the pole’s central part at high flux density levels and homogenize the field distribution in the aperture. The present design considers a coil which is powered by a MIC cable. Figure 2.4.42 and Figure 2.4.43 show the present layout of both quadrupole magnet types. ∆B/B Figure 2.4.42: Front, side, and back view of a normal conducting radiation resistant quadrupole having a pole tip radius of 100 mm for the 1 st stage of the Pre-Separator.

Dimensions are given in mm. 2.4.2.2.2 Superferric quadrupole magnets Each dipole stage of the Super-FRS is equipped with a quadrupole triplet in front and behind the dipole magnet. The standard quadrupole triplet consists of 3 cold-iron, superferric quadrupole magnets with warm aperture radius of ± 190 mm. Their lengths is 800 mm, 1200 mm, and 800 mm and provide a maximum field gradient of 10.0 T/m. The distance between two quadrupoles is 1000 mm. Octupole correction coils are embedded in the 800 mm long quadrupole magnets to allow corrections of image aberration. The three quadrupole magnets will be assembled in one common cryostat together with up to three 500 mm long superferric hexapole magnets and 500 mm long superferric steering dipoles. One example for such a multiplet consisting of three quadrupoles and two hexapoles is schematically illustrated in Figure 2.4.44. All magnets in the cryostat are cooled with liquid helium in a common helium bath. The same principle is used for the A1900 quadrupole triplet [16] and the quadrupole triplet for the BigRIPS [17]. Figure 2.4.44: Schematic view of a Super-FRS multiplet structure consisting of a quadrupole triplet with octupole correction coils and two hexapole magnets. All magnets are located in a common cryostat. Hexapole magnets can also be inserted between two quadrupoles (indicated with dashed lines). 45
