Abstract Body

High-temperature superconducting (HTS) magnets are advantageous due to their ability to support large electrical current densities and generate strong magnetic fields with low power consumption in a compact coil packet. This work introduces a new type of HTS magnet which incorporates a unique Bitter-like coil architecture and is constructed from rare-earth barium cuprate (REBCO) bulk HTS material. The design and development of the magnet are described, including its joints and terminals. Experimental results obtained from initial tests of the prototype magnet are presented, and the potential applications and advantages of this new coil design are discussed. These results promise a new path for compact, high-stability high-field magnets with low power consumption.
