High-T
A superconducting electromagnet and method for manufacturing, using, monitoring, and controlling same are disclosed. Embodiments are directed to a superconducting electromagnet that includes a superconductor tape including: a first unslotted end; a second unslotted end; and a longitudinally slotted section provided between the first unslotted end and the second unslotted end. The longitudinally slotted section includes a first longitudinal part and a second longitudinal part. The first longitudinal part is provided in a wound manner thereby defining a first coil. The second longitudinal part is provided in a wound manner thereby defining a second coil. These and other embodiments achieve persistent current operation of the superconducting electromagnet without the need for solder joints within the magnet coil itself, which can result in improved stability and reduced power consumption.
