In this paper, a new configuration of self-shielding DC HTS cable with a “sandwich” structure by interleaving winding is proposed. The distributions of the magnetic field and the critical currents in traditional DC HTS cable and self-shielding DC HTS cable are analyzed and compared in detail. The simulation results show that the self-shielding DC HTS cable can minimize the outer magnetic field...

High field magnet technologies are supported by the development of advanced superconducting (SC) cable constructed from the composite SC tape. The SC tapes in the helically wound composite cable experience flatwise as well as edgewise bending load together with tensile one. We analyzed precisely the influence of uniaxial tensile load to critical current (Ic) of BSCCO tapes, where the...

China Fusion Engineering Experimental Reactor (CFETR) is a major scientific project independently designed and developed by China and jointly with international cooperation. Engineering design and project infrastructure construction are currently underway. The design goal of CFETR is 1.5-2.0 GW fusion power, and the central magnetic field is up to 17 Tesla, which is much larger than the design...

Bi-2212/Ag round wires are promising conductor candidates for the development of high-field magnets up to 25 T. With very high upper critical magnetic field and critical current density, Cable-In-Conduit Conductor (CICC) comprised of Bi-2212/Ag superconducting wires is under designing for the central solenoid coils of the China Fusion Engineering Test Reactor (CFETER). The current degradation...

High-temperature superconductors (HTS) are being considered for considered for use in high field dipole and quadrupole magnets for future particle accelerators. In comparison with low-temperature superconductors (LTS), the persistent current magnetizations of HTS are much larger. Because of this, the magnet error fields are much larger (since they depending on the size and shape of the...

High-temperature superconducting (HTS) tapes in a superconducting cable are twisted and stacked as multi-layer. The superconducting tapes are exposed to a combined magnetic field of the circumferential magnetic field created by the inner layers and the longitudinal magnetic field created by the twisted outer layers. The AC loss in superconducting tapes under HTS cable electromagnetic...

Bi-2212 conductor is now a serious candidate for HEP, NMR, and other ultra-high field magnet applications since our demonstration that 50 bar over-pressure heat treatment (OPHT) is reliable and predictable for many coil reactions. As more magnet designs are generated, predictable and consistent critical current density ($J_{\text{c}}$) values are important too. In fact there are still...
