Estimating the term…
A magnet coil (30) comprises at least one first winding made of wire (34) which is superconductive at operating temperature and at least one second winding made of normally conductive wire (36). In addition, means are provided for supplying a current into the second winding, which is completely dead during superconductive operation of the magnet coil (30), when at least certain sections of the superconductive wire (34) assume the normally conductive state. In order to accelerate the spatial propagation of this transition in the magnet coil (30) and at the same time to provide the possibility to use low-cost wires having a relatively small proportion, related to the cross-sectional area, of normally conductive material, the first and the second winding are connected in parallel electrically.
A magnet coil having at least one first winding made of wire which is superconductive at operating temperature, said first winding being comprised of a plurality of serially connected first winding sections, and at least one second winding made of normal conductive wire, said second winding being comprised of a plurality of serially connected second winding sections, each one of said second winding sections being connected in parallel to one of said first winding sections, wherein each second winding section is arranged within the magnet coil in spaced relationship with respect to the first winding section to which it is connected, so that each second winding section of normal conductive wire is provided in effective heat-conducting contact with at least one additional first winding section of superconductive wire.
