Abstract (en)

A plurality of superconductive coils are disposed in parallel with superconductive switching elements to form a plurality of superconductive current loops. The current loops are connected by bridging conductors connecting the current loops so that the superconductive coils are connected in series. The circuit is energized by establishing a main current in the series connected superconductive coils with the superconductive switches in the ohmic state. The switches are then switched to the superconductive state when the desired current level is reached. The main power supply is then removed. Adjusting currents are subsequently independently established in the superconducting loops as needed. With this circuit and method, a means is provided for establishing high uniformity magnetic fields. As an additional benefit, the present method offers significant manufacturing advantages in the testing of superconductive joints.
