Superconductive highly field magnet coil with hts - coils section and production method

摘要

A superconductive highly field magnet coil with several solenoid, multilayer, about a common central axis a in layers on a hollow cylindrical support body (3) wound coils sections which are electrically connected in series and a current of more than 100 a to be able to bear, is characterized in that the radially innermost coils section (1) superconductive wire (2), the oxidic high-temperature superconductor (= hts) - material, wherein the layers of the radially innermost coils section (1) are wound helically in such a way that between the windings of a free axial distance, which is filled. The corresponding production method comprises the following steps: dollars a (a) helical winding of a layer of superconductive hts - wire together with a discontinuity wire on the support body; dollars a (b) removal of the discontinuity wire from the support body; dollars a (c) repeating steps (a) and (b) until the desired number of layers of the coils section is reached; dollars a (d) heat treatment of the winding packet to react of the hts - material under o φ 2 φ - containing gas atmosphere with optimized glow parameters; dollars a (e) casting of the cavities of the coils section. Dollars a it is thus possible to produce a nmr - and is capable of solenoid coil, which is only a few superconducting compounds, topologically is of simple construction, a current of a few hundred amperes and can carry hts - material, so that they can generate magnetic fields of & 21 tesla.
