APPARATUS FOR MEASUREMENT OF CRITICAL CURRENT IN SUPERCONDUCTIVE TAPES

摘要

A cryogenic linear positioner which is primarily used for characterizing coated conductor critical current homogeneity at 75K is disclosed. Additionally, this tool can be used to measure the positional dependence of the coated conductor resistance at room temperature, and the room temperature resistance of the underlying YBCO coating without the overlaying protective cover of silver.
