Filed: 1991-03-25
Abstract: PURPOSE:To suppress the generation of heat caused by an eddy current against a change in a magnetic field without deteriorating the start-up time for setting a superconducting state so as to prevent the occurrence of quenching of superconductivity by constituting a superconducting coil container in such a way that at least part of the container is constituted of a high resistance section having a resistance which is higher than that of the other section. CONSTITUTION:Most part of a superconducting coil container is constituted of a low-resistance material and the surrounding areas of two points in a supporting member fitting section 12 are constituted of a high-resistance material 11. Accordingly, an eddy current 13 generated in the peripheral direction of the container at the time of rising for setting a superconducting state flows around the low-resistance section 10 only and a little of the eddy current 13 flows to the high-resistance section. Therefore, the eddy current 13 which flows in the same direction as the current flowing through the superconducting coil becomes smaller and the electromotive force which interrupts an increase in the current flowing through the superconducting coil is also reduced.
