我们描述了一种新的用途超导磁通泵，即磁化的平面磁场源的方法。该方法是有用的许多应用，但我们说明它与平面潘宁陷阱在量子技术中的应用。本文描述了一种磁通泵送机理及其数学模型。该方法允许完全控制双环超导结构中的感应持续电流，由此最终电流是所施加的通量和环几何形状的已知函数。我们已经测试了我们的磁通泵技术，发现与理论非常吻合。
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.
