In this study, we present the understanding of magnetic stress in REBCO (Rare Earth Barium Copper Oxide) magnets, based on experimental results from a 26.4 T magnet [1] and a 45.5 T magnet [2]. Magnetic stress in a high-field magnet is a critical factor that can affect their overall performance and reliability. We address three approaches for developing an understanding of magnetic stress in...
Since 2G HTS tapes have excellent features such as high in-field critical current (Ic) and tensile strength, they are suitable for various applications including high-field magnets. Fujikura Ltd. has developed high-performance 2G HTS tapes using IBAD and PLD techniques, and has supplied to many customers for years. In particular, the hot-wall PLD system that we have developed enables highly...
Ultrahigh field high-temperature superconducting (HTS) magnets beyond 20 T have been developed worldwide. Rare-earth barium copper oxide (REBCO) coils are promising in terms of their high-field specifications as insert coils. However, mechanical damages of REBCO tapes are getting critical in spite of high stiffness of Hastelloy substrates. Plastic deformations have been frequently observed...
The heterogeneous nature of REBCO Coated Conductor (CC) properties poses significant challenges in the fabrication of high magnetic field devices. Our goal is to peer below the cartoon representations of CC so that, amongst other things, we might better understand whether a CC from one manufacturer is interchangeable with that from another. This involves knowledge of a broad range of...
