2.4.2.3 Multipoles DRAFT Table 2.4.16 lists the specification of the higher order magnets used in the Super-FRS. The table is subdivided into hexapole magnets (radiation resistant as well as superferric) and into the octupole correction coils, which are embedded into the 0.800 m long superferric quadrupole magnets. Although all magnets will be operated in a DC mode the iron design has to be considered to be build by laminations since the Bρ setting of the Super-FRS has to be changed frequently according to the experimental requirements.

DRAFT 2.4.2.3.1 Radiation resistant hexapole magnets It is planned to be built the radiation resistant hexapole magnets as normal conducting magnets using MIC cables, like for the radiation resistant dipole and quadrupole magnets. Two of such hexapole magnets are required, one before the first dipole unit and one behind the third dipole, close to the first focal plane PF1. The hexapole magnets have a pole tip radius of 200 mm (useful aperture is 190 mm) achieving a hexapole component of 34 T/m 2 . Design of the sextupole magnet Figure 2.4.55 shows a 3D view of the radiation resistant hexapole. The iron yoke is divided into six parts, fixed together with bolts and dowels. Each part of the iron yoke consists of separate lamellae with radiation-resistant insulation on their surfaces. The lamellae are welded together over the external surface of the hexapole magnet and special studs and hooks additionally tighten them together in the pole area. Thus the magnetic field in the hexapole magnet does not pass through close circuits in the iron yoke. The diameter of the circle inscribed between the magnet poles should be observed with accuracy better than ±100µ. The distances between neighboring poles should be observed with accuracy better than ±50µ. It is planned to equip the hexapole magnet with two water feeding and collectors, allowing separate supply of water to each current coil cooling pipe (see Figure 2.4.56). The coils are electrically connected in series so that assembling or dismantling two halves of the hexapole magnet it will be sufficient dismantle only one connection of the copper bus-bar (see Figure 2.4.55). Figure 2.4.55: 3D view of the radiation resistant hexapole magnet. Electric circuit (right side) and water cooling circuit (left side) are separated from each other. 53
