Research on Spatial Distribution and Mutual Inductance of Superconducting Pancake Coils

Abstract:

This paper studies the numerical calculation method of mutual inductance between two superconducting pancake coils. And the calculation results are proved through experiment. Use this calculation method, the isoline map of two superconducting pancake coils’ coupling coefficient with the different spatial distributions is calculated. Then the designer can rapidly design the spatial distribution of superconducting pancake coils according to the coupling coefficient they needs. Specially, there is a curve of coupling coefficient equals 0 in the isoline ma. For the occasions which want to eliminate the mutual inductance between two superconducting pancake coils, this curve can provide a good guidance for design a compact layout and reduce the volume. Finally, the 0 value curve is tested under the guidance of calculation result. Through this experiment, the correctness and engineering guidance of isoline map is verified.
