Stabilization of a Superconducting Magnet Wound by a High Tc Oxide Conductor

  • Hideaki Maeda
Conference paper


Potential problems of stabilization and protection for a high Tc oxide superconducting magnet are examined. Firstly, both magnetic and mechanical disturbances, appearing during magnet charging, are discussed; allowable conductor dimension is given based on the adiabatic stability criterion. Secondly, effect of cryogenic stabilization is compared with the case of conventional superconducting magnet at 4.2 K. Finally, magnet protection during coil quenching is examined.
