Abstract
YBa2Cu3O7−x (YBCO) coated conductors are realized by the deposition of a YBCO film atop thin (10−6 m) ceramic buffer layers, previously deposited upon a high resistance nickel alloy. On the other side of the tape a copper layer is often added to create an alternative current path during quenches. Several investigations have shown a different qualitative behaviour of the voltages measured on the nickel and copper sides of the tape. In this work we give a theoretical explanation for this phenomenon and point out the technical consequences it might have for the design of devices constructed using YBCO coated conductors.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
