HIGH TEMPERATURE SUPERCONDUCTING TAPE CONDUCTOR HAVING HIGH CRITICAL AMPACITY

摘要

The invention relates to a high temperature superconducting tape conductor having a flexible metal substrate that comprises at least one intermediate layer disposed on the flexible metal substrate and comprising terraces on the side opposite the flexible metal substrate, wherein a mean width of the terraces is less than 1μm and a mean height of the terraces is more than 20 nm, and that comprises at least one high temperature superconducting layer disposed on the intermediate layer, which is disposed on the at least one intermediate layer and comprises a layer thickness of more than 3μm. The ampacity of the high temperature superconducting tape conductor relative to the conductor width is more than 600 A/cm at 77 K.
