The parallel-wound No-insulation (PWNI) high temperature superconducting (HTS) coil is a novel type of pancake-shaped no-insulation coil made by parallel-staked HTS tapes, which is a promising solution for high field magnets. Previous studies have analyzed the electromagnetic characteristics of a PWNI HTS coil during the ramping process through simulations. The current distribution of these...
In the context of accelerator and fusion magnet applications, high-temperature superconducting (HTS) coils must maintain stable performance over extended periods post-installation, during which they undergo multiple thermal and magnetic cycles. This study investigates the stability of REBCO MI/NI coils under repeated thermal cycling and periodic electromagnetic loading. The degradation of Ic...
An improved non-destructive detection method for detecting the turn-to-turn resistivity(TTRD) of large non-insulated REBCO coils is proposed. In previous studies, a method based on ODE and GA algorithm is proposed but tested only in a circular experimental coil. This study improves the method by modifying the optimization algorithm and detecting process to raise robustness, and tests in a...
