SUPERCONDUCTING MAGNET FOR MAGNETIC-LEVITATION RAILWAY VEHICLE |
| 摘要 |
<p><P>PROBLEM TO BE SOLVED: To provide a lightweight and high-reliability superconducting magnet for a magnetic-levitation railway vehicle. <P>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. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
