Abstract: Disclosed is a saddle-shaped coil winding which is formed onto an outer tube surface from a planar race track-type coil shape so as to be provided with axially extending winding sections on the longitudinal side and winding sections that extend therebetween, are located on the front side, and form winding overhangs. The individual windings of the coil winding are to be formed with at least one band-shaped superconductor which comprises especially high Tc superconductor material and whose narrow side faces the outer tube surface. In order to prevent unacceptable mechanical stresses of the conductor when forming the coil, the windings in the saddle shape have a circumferential length which is virtually unchanged from the length in the planar oil shape.

Abstract: A method for manufacturing melt materials of copper, chromium, and at least one readily evaporable component as well as a fusible electrode for using this method is disclosed.More specifically, an arc melting method is used for the manufacture of melt materials based on copper and chromium in which the electrode material melting off a fusible electrode of given resultant composition is collected in a water-cooled permanent mold for the purpose of cooling down without macroscopic separation of copper and chromium.A fusible electrode for use in this method is also provided. This fusible electrode partially consists of a solid alloy of copper with the readily evaporable component.
