Title:
【発明の名称】傾斜機能材を用いた超伝導コイル用電流リード
Document Type and Number:
Japanese Patent JP3007956
Kind Code:
B2
Abstract:
Current leads are used for connecting a power supply (100) placed in a room-temperature environment and a superconducting coil (200) placed in an ultralow-temperature environment. The current leads includes a first current lead (31a) and a second current lead (31b). The first current lead (31a) is made up of a room-temperature N-type thermoelectric semiconductor (32a), a low-temperature N-type thermoelectric semiconductor (33a), and a high-temperature superconductor (34). The second current lead (31b) is made up of a room-temperature P-type thermoelectric semiconductor (32b), a low-temperature P-type thermoelectric semiconductor (33b), and a high-temperature superconductor (34). At least one of the first and second current leads is formed of a functionally gradient material.
