| contents | The magnetization of ReBCO tape stacks and tape stack cables in high magnetic fields (up to 30 T) are not commonly reported. Here we report magnetization measurements of tape stack cables in magnetic fields up to 30 T at 4.2 K. We observed that flux jumps, commonly relegated to low field regimes for single tapes, persisted up to 17 T in tape stacks, an effect which could have substantial technological relevance for high field applications including fusion devices or accelerator magnets. On the other hand, with the use of small spacers, we could suppress flux jump behavior, in some cases eliminating jumps entirely. Our findings provide critical insights for the optimization of designs for ReBCO cables for high-field applications, including fusion magnets and particle accelerators. |
