Abstract-in this paper, the application feasibility of HTS tapes on tokamak magnets is discussed and the existing four kinds of HTS high current conductors are summarized. Furthermore, an YBCO conductor structure suitable for a 10 GJ tokamak TF magnet is designed and the current carrying capacity is evaluated. The simulation result shows that the critical current of the YBCO conductor is about 75 kA @ 10 T, 30 K.

“…However, Bi-2212 is not favored for applications other than magnets, and manufacturers are concentrating on improving the characteristics and increasing the yield of the Y-123 tape due to its better potential for cost reduction. It is therefore indicated to investigate the use of tape conductor for magnets, and in this respect the test results of fully-transposed Roebel cables made from tape are encouraging 13,14) .…”

Synopsis:With the continuing improvement of properties of High T c Superconductors (HTS), their application to accelerator technology is becoming increasingly attractive. While the medium to long-term goal for their use in this field will be for high field magnets, the materials now available enable a number of specific applications which benefit from their characteristics and make them a valid alternative to conventional Low T c Superconductors (LTS). If devices for electrical utilities generally seek to use nitrogen as cryogen, large superconducting accelerators rely on helium cryogenics, and allow operating at lower temperatures with consequent gains in electrical performance and temperature margin. After an overview of commercial HTS materials, applications of HTS to accelerators are presented, with examples of present and future use of HTS in the Large Hadron Collider.

“…The Roebel geometry is the most promising cable geometry for flat HTS coated conductors. However, if short twist lengths have to be realized to reduce coupling losses, these conductors have to be brought into a meander-like geometry by punching or cutting techniques due to the bad bending properties in the tape plane [2]. For MgB 2 , mono-and multifilament conductors with high current carrying capacity have been developed in the past years, however, not many efforts have been made to develop wires or cables with reduced ac losses.…”

Since the discovery of superconductivity in MgB 2 many efforts have been undertaken to improve the current carrying capacity of mono-or multifilament MgB 2 conductors. However, even though MgB 2 conductors can be produced in geometries which easily allow twisting or cabling, the reduction of ac losses has often played a minor role, even though many technical superconductor applications like transformers, rotating machinery, and ramped magnets require conductors with low AC losses. In this paper we present short cables together with measured AC-losses applying a simple cabling technique. Coupling losses of the cables with strands having a single component stainless steel (SS) sheath are negligible. The lower apparent measured losses of cables with Nb/Cu/SS sheaths may be explained by magnetic shielding of the Nb layer and by a systematic problem of the magnetization method for samples containing diamagnetic and ferromagnetic components.
