测量了通过超导链路并联的两个约瑟夫森结的最大超电流，发现电流的调制是周期性的，其周期非常接近通量量子（h/2e），与均匀磁场产生的周期相同。磁通是由一个紧密缠绕的螺线管产生的，该螺线管布置成没有净轴向电流。实验证明了磁场效应可以忽略的静态矢量势所产生的效应。(R.E.U.)
The maximum supercurrent flowing through two Josephson junctions connected in parallel by superconducting links was measured, and the modulation of the current was found to be periodic with a period very nearly the flux quantum (h/2e) and identical with the period produced by a uniform magnetic field. The flux was produced by a closely wound solenoid arranged to have no net axial current flow. The experiment demonstrates the effect produced by a static vector potential with negligible magnetic field effects. (R.E.U.)
