We describe a novel use for superconducting flux pumping, namely a method for magnetizing a planar magnetic field source. The method is useful for many applications, but we illustrate it with the planar Penning trap with applications in quantum technology. A flux pumping mechanism and associated mathematical model are described. The method allows for complete control of the induced persistent current in a double-loop superconducting structure, whereby the final current is a known function of the applied flux and the loop geometry. We have tested our flux pumping technique and found excellent agreement with the theory.

用于平面磁场源的超导磁通泵

我们描述了超导磁通泵浦的一种新用途，即一种用于磁化平面磁场源的方法。该方法对许多应用都很有用，但我们用平面 Penning 陷阱在量子技术中的应用来说明它。描述了通量泵送机制和相关的数学模型。该方法允许完全控制双回路超导结构中的感应持续电流，由此最终电流是所施加通量和回路几何形状的已知函数。我们已经测试了我们的通量泵技术并发现与理论非常吻合。
