Technical Design Report Super Fragment Separator

DRAFT
current of typically 1000 to 3000 A and an engineering current density between ≈ 2 to ≈ 5 A/mm 2
can be achieved. Magnets using MIC cable are used already in other laboratories [14].

Figure 2.4.19 shows the cross section and top view of the radiation resistant dipole magnet based
on a MIC cable with a conductor size of (19 x 19) mm 2 . The core of the dipole magnet consists of
two divisible halves (Figure 2.4.20) where each half is subdivided into three units made of steel
plates and having thicknesses between 120 to 140 mm which are welded together. One unit weighs
13 tons thus the whole core weighs 78 tons.

possible solution of a normal conducting radiation resistant dipole for the 1 st stage of the Pre-Separator. The
dimensions are given in mm.
