Abstract
In the search for axion dark matter, superconducting rf technology is important for fabricating microwave cavities with high $Q$ factors, but the presence of a strong external magnetic field leads to technical difficulties. This study presents a polygonal design with tapes of high-temperature superconductor to realize a superconducting resonant cavity that shows no considerable degradation in magnetic fields up to 8 Tesla. This approach could impact engineering solutions to improve dark-matter detection and other research areas requiring low cavity loss in a strong magnetic field.
