Title:
METHOD FOR INCREASING CURRENT TRANSPORTATION CAPACITY OF HIGH-TEMPERATURE SUPERCONDUCTOR
Document Type and Number:
Japanese Patent JP3195184
Kind Code:
B2
Abstract:
PURPOSE: To increase the current transportation capacity of a high TC superconductor substance, by irradiating high-temperature superconductive substance with light particles, and making the element within the superconductor substance bring fission into existence thereby forming a columnar defect dispersed greatly in each direction.
CONSTITUTION: A high-temperature superconductor, which has one or more kinds of elements fissioning by light particles, is prepared. This high-temperature superconductor is irradiated with light particles which have enough energy for contained elements to cause fission. Hereby, a columnar damaged defect which extends, being dispersed in each direction on high level is made within the superconductor. By the formation of this defect, the magnetic vortex generated within the superconductor is pinned, and a superconductor bulk line material which has large current transformation capacity can be obtained.
