Two cases are indicated: a high field of 1.6 T (light blue) and a low field of 0.15 T (dark blue), respectively. To achieve Bmax = 1.6 T for a gap height of 180 mm a total current of NI = 129 kA is required. The dipole magnet has two main current coils (Figure 2.4.22). Each coil consists of four independent sections. Each section contains a water-cooled radiator and 4 layers of radiation-resistant copper cable, two layers from each side of the radiator. The current coil section is encapsulated in tin solder in a special vacuum mould. The cross-section of current coil is shown in Figure 2.4.23. Figure 2.4.22: Top view of the coil for the radiation resistant dipole. 28
DRAFT Figure 2.4.23: Coil cross-section indicating the four layers and the four water-cooled radiators. One coil section consists of 48 turns of radiation-resistant cable with an average length of L ≈ 8.75 m. The cable length in one section is thus approximately 400 m and in total the magnet requires about 3200 m of radiation resistant copper cable. The cross-section of the radiation-resistant cable is (19 ×19) mm 2 . The cable consists of the central copper core with a cross-section of S = 190 mm 2 , a magnesium oxide interlayer of 1÷1.5 mm, and a copper envelope of approximately 1 mm thickness. The total resistance of two coils connected in series is 0.32 Ohm. The power consumption of one section of the coil will be 18 kW and thus the total power consumption of the whole magnet will be approximately 144 kW at maximum field. The voltage drop across two coils connected in series will be 215 V. The water-cooled radiator consists of a 10 mm thick plate including three milled grooves where stainless steel tubes are incorporated (Ø 6 mm inner diameter, Ø 8 mm outer diameter). Each tube is connected independently to the water conduit but in parallel to the other tubes. The weight of one coil section is approximately 1.4 tons, thus in total each coil weighs about 5.6 tons. 2.4.2.1.2 <strong>Super</strong>ferric dipole magnets The main design parameters of the superferric dipole magnets for the <strong>Super</strong>-FRS are: • DC operation, • warm iron and warm bore (including warm vacuum chamber), • large pole gap (170 mm), • moderate maximum field (1.6 T). 29
