DRAFT Figure 2.4.35: Left panel: Cryostat with plate, observation ports and supports. Right panel: Support structure. 2.4.2.1.3 <strong>Super</strong>ferric dipole magnets for the Energy Buncher 2D-Magnetic design The dipoles for the Magnetic Spectrometer and Energy Buncher at the exit of the Low-Energy Branch are also superferric magnets with warm iron but SC coils. To guarantee the required resolving power of the facilities the magnets must have a large magnetic volumes. The specifications of the dipole magnet are listed in Table 2.4.8 and its cross section is shown in Figure 2.4.36. Figure 2.4.36: Cross section of one Energy Buncher dipole unit. 38
DRAFT To fulfill the required field quality over the whole range of operation from 0.15 to 1.6 T air slots were introduced in the pole shoes. Their location is listed in Table 2.4.12. The air slots are not symmetrical with respect to the magnet center. Table 2.4.12: Coordinates of the air slots corners. air slot left side air slot right side x [m] y [m] x [m] y [m ] 4.195 0.185 4.465 0.185 4.195 0.195 4.465 0.195 4.245 0.195 4.515 0.195 The coils have a dimension of 40 mm × 40 mm and their position is given by the coil center coordinates, which are: left side coil: xl = 3.615 m, yl = 0.17 m right side coil: xr = 5.100 m, yr = 0.17 m The maximum current density in the coil is 104 A/mm 2 . Figure 2.4.37 illustrates the field properties of the magnet for different B-values. Especially for low B-field values - but also for very high B-field values - the design has to be further improved to fulfill the field specifications. In principle the field quality may be improved by: • introducing a gap between the yoke and the pole (Purcell filter); • correcting coils on the pole surface. The maximum field in the coil area is 1.9 T. The load line for the magnet is shown in Figure 2.4.38 and Table 2.4.13.
