“…Table 1 lists key parameters of the CCs among manufacturers. The RE123 layer can be deposited either by chemical routes, such as metal organic deposition (MOD) [23] and metal organic chemical vapor deposition (MOCVD) [24], or by physical routes, such as pulsed laser deposition (PLD) [11,16,25,26] and reactive co-evaporation (RCE) [15,22]. MOD and RCE are ex situ processes incorporating two steps: deposition of the precursors and subsequent conversion of the precursors into RE123.…”

Recent progresses in the second generation REBa 2 Cu 3 O 7 − x (RE123) coated conductor (CC) have paved a way for the development of superconducting solenoids capable of generating fields well above 23.5 T, i.e. the limit of NbTi−Nb 3 Sn-based magnets. However, the RE123 magnet still poses several fundamental and engineering challenges. In this work we review the state-ofthe-art of conductor and magnet technologies. The goal is to illustrate a close synergetic relationship between evolution of high-field magnets and advancement in superconductor technology. The paper is organized in three parts: (1) the basics of RE123 CC fabrication technique, including latest developments to improve conductor performance and production throughput; (2) critical issues and innovative design concepts for the RE123-based magnet; and (3) an overview of noteworthy ongoing magnet projects.

“…It consists in partial Ni or Ni-alloy replacement by non-magnetic material such as SS. For example composite tape can consist of 2 layers: thin Ni textured layer and thick SS AISI 316 L layer [11]. At Ni:SS volume ratio 1 : 5 the tape must have M sat value by a factor of 6 less than in pure Ni and is comparable with such values for homogeneous Ni-W tapes with ∼7 at.% W. But nevertheless such M sat values are not low enough for many applications.…”

Substrate materials are the key element of the coated conductors. There are two types of substrates-nontextured (stainless steel (SS) or Hastelloy alloys) and textured ones which are based on the Ni-W alloys. The main requirements for the textured tapes (RABiTS) are the presence of the highly pronounced biaxial cubic texture {100} < 100 > and low values of magnetic susceptibility. To realize these requirements RABiTS tapes of various kinds were developed-homogenous tapes from Ni-W alloys with W content 5.5-9 at.% and composite ones. Composite tapes consist of three layers-one of SS and two of Ni-W alloy with W content 6 at.%. Mechanical and magnetic properties of the tapes were investigated and the dependence of tapes texture quality from total accumulated deformations was studied. The ultimate tensile strength value of composite tapes was 750 ± 10 MPa. The conditions necessary to form the required {100} < 100 > texture are different for the homogeneous and composite tapes. According to the magnetic measurements saturation magnetization of composite tapes is about a factor of two lower than for similar homogeneous tapes.

“…On this substrate buffer layers grow bi-axially easily and rapidly, and therefore, fewer buffer layers are needed compared with the ion beam assisted deposition (IBAD) substrate. Our substrate is clad-type which has high mechanical property and low saturation magnetization [2].…”
