“…Therefore, one of the crucial issues is minimization of their number and resistance within the windings of the HTS undulator. For the planar undulator concept a solution to joint-less winding has been proposed by Kim et al [7].…”

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.

“…This means that it is possible to deal with a larger beam heat intake, making the operation of the magnet more robust. Moreover, operation of the magnet at higher temperatures than 4 K translates into a more efficient way to remove heat loads.HTS tapes, especially rare earth-barium copper oxide (REBCO) coated conductors, can be used for planar SCUs in geometries similar to the ones used for NbTi wire [2][3][4]. The recent paper [4] explores applying HTS tapes to such a geometry.…”

Recent advances in second-generation (2G) high temperature superconducting (HTS) coated conductors (CCs) have made them very attractive for new applications such as undulators. In this paper, we have, for the first time, experimentally evaluated a design to validate applicability of 2G-HTS tapes for next generation undulator magnetic structures. A two-period undulator magnetic core was fabricated and 2G-HTS CCs were successfully wound onto the undulator core. The performance of the undulator magnetic structure was investigated and the highest engineering current density, Je, in such configuration reported yet was obtained. A new U-slit tape configuration was used to reduce the number of resistive joints and it was shown that with this new technique affordable levels of resistance values can be achieved for short length undulators. The ferromagnetic core was designed such as to accommodate winding the U-slit tapes. Test results indicated that the winding and the soldering procedures are successful and do not deteriorate the performance of the 2G-HTS tapes.
