| 简介 | PROBLEM TO BE SOLVED : To provide a lightweight and high-reliability superconducting magnet for a magnetic-levitation railway vehicle. SOLUTION : A superconducting magnet for a magnetic-levitation railway vehicle is provided with superconducting coils 2 made of a rare-earth-element-based high-temperature superconductor. The superconducting coils 2 are cooled to below a temperature, at which a superconducting state occurs, only by a one-stage refrigerator 5. COPYRIGHT : (C)2009, JPO&INPIT | ||
