Title:
超電導装置
Document Type and Number:
Japanese Patent JP4598855
Kind Code:
B2
Abstract:
A superconducting apparatus includes a magnetic field generating portion including a superconducting coil, an extremely low temperature generating portion maintaining the superconducting coil at an extremely low temperature and in a superconducting state, a container defining a heat insulation chamber that accommodates the superconducting coil, a first terminal electrically connected to the superconducting coil and supplying an electric power to the superconducting coil, a second terminal connected to an external electric power source and supplying the electric power to the first terminal in a case where the magnetic field generating portion is driven, and a heat penetration preventing element holding one of the first and second terminals and thermally separating the first and second terminals from each other in a case where a driving of the magnetic field generating portion is stopped, the heat penetration preventing element restraining a heat penetration from the second terminal to the first terminal.
