The large-scale superconducting magnet in controlled nuclear fusion systems and accelerators are key components for achieving high magnetic fields. As a superconducting conductor made from high-temperature superconducting (HTS) tapes, quasi-isotropic strand (Q-IS) exhibits quasi-isotropic properties such as thermal and mechanical stability as well as making it an ideal choice for application...
High-temperature superconducting (HTS) Twisted-Stacked-Tape-Cable (TSTC) conductors have been developed for use in high-field magnets, particularly those needed for compact, high-field fusion tokamaks. TSTC conductors generally contain a large number of simply-stacked RE-Ba2Cu3O7-x (RE=rare earth) (REBCO) coated conductors inserted into helical channels in a round former. Multiple versions...
The integration of high-temperature superconductors (HTS) into fusion coil systems is a key advancement for magnetic confinement fusion technology. HTS conductors provide significant benefits, including higher operational thresholds for temperature, transport current, and magnetic fields, which are pivotal for future fusion applications. A previous study introduced an innovative HTS sector...
High-temperature superconductors (HTS) coil systems are currently being considered within the context of magnetic confinement fusion for enabling higher operating temperatures, increased transport currents, and stronger magnetic fields. For the DEMO Central Solenoid coil, a novel HTS sector cable-in-conduit conductor (CICC), targeting 60 kA at 4.5 K and 18 T, has been proposed recently. In HTS...
Strong magnetic fields might be crucial for enhancing the performance of nuclear fusion devices. High-temperature superconducting (HTS) tapes have emerged as promising materials due to their capability of carrying high current densities in high-magnetic field environments. Alongside with various types of HTS conductors for fusion proposed by numerous research institutions, in our previous...
The slotted core configuration is a promising candidate for the implementation of High-Temperature-Superconducting (HTS) magnets in compact fusion reactors. Quench dynamics is not yet fully understood in this type of cable and experimental and numerical investigations are still required to fully characterize their behavior in the operative conditions relevant to fusion machines.
In this work,...
The complexity of tokamak machines requires virtual alignment studies from the design until the assembly phase. The component variability after manufacturing can cause deviations of the components from their nominal design with consequent installation misalignments. Proper positioning and alignment of the as-built tokamak components, such as magnets, vacuum vessel and in-vessel components, to...
