Description
High-temperature superconducting (HTS) coated conductors (CCs) have become increasingly available for high-field magnet applications, thanks to continual advancements in manufacturing. Previous studies have revealed that HTS CCs, characterized by their anisotropic lattice structures, exhibit a critical current density that strongly depends on the angle between the magnetic field and the tape surface. This angular dependency poses both challenges and opportunities for optimizing HTS-based magnet designs. In this work, using the experimental data from the literature, a conventional pancake coil is optimized by tilting the tapes to achieve a more favorable angle between the magnetic field and the tape surface, thereby improving the critical current density distribution without compromising the field quality. This enhancement can reduce the quench risk in HTS coils. A comparison between the optimized coils and traditional pancake coils is presented. How these results can inform the design of more complex coil geometries is discussed.
