Experimental Investigation of High-Temperature Superconducting Magnet for Maglev
نویسندگان
چکیده
The use of high-temperature superconducting wires (HTS wires) in on-board superconducting magnets for maglev has several advantages such as improvement in the stability of the superconducting magnet, improvement in reliability through simplification of the magnet structure, and decrease in the mass of the superconducting magnet and energy consumed by the on-board cryocooler. To demonstrate the applicability of HTS wires, we developed a cryocooler-free high-temperature superconducting magnet using HTS wires approximately one-quarter the size of a full-scale on-board superconducting magnet. This magnet can generate a magnetic field stronger than 1 T at a coil temperature of 50 K, and it has a cold insulation performance that can keep the coil temperature lower than 50 K for more than 8 h after initial cooling.
