Basic study of high T_c superconducting magnet excited by thermoelectromotive force

摘要

This paper describes experimental results of a high T_c superconducting magnet excited by a thermoelectromotive force. This magnet system has an advantage of simple configuration because a thermoelectric element is much smaller than a conventional external power source for a superconducting magnet. It is demonstrated that more than 50 A of transport current is obtained in the present experiment. The heat leakage to the coil is about double amount as compared with a conventional magnet system with an external power source.
