Magnetic Performance of a Laser Structured YBCO Tape Suitable for Insertion Devices Technology

Recent intensive development of high-temperature superconducting (HTS) materials resulted in the availability of various commercial HTS tapes, in particular coated conductors. Technological progress in this field and up-coming market will reduce the costs of the tape. One very promising application for free electron laser technology considers a new concept of meander-like structured stacked HTS tapes to provide the desired magnetic field pattern with periodic changing field orientation. For the first time, we report in this paper on the magnetic field performance of such an HTS tape, structured with picosecond laser pulses, which prevent damage of the superconducting layer by overheating and lead to very precise structure.
