Description
With the beneficial characteristics of high irreversible field, high superconducting transition temperature and high critical current density, REBCO material has reached the stage of mass commercial production. Meanwhile a large number of superconducting power transmission projects and superconducting magnets have been developed using REBCO tapes. Recently, due to the significant demand for REBCO tapes by compact fusion industry, Shanghai Superconductor Technology Co., Ltd. (SST) has kicked off a new round of production expansion. Through independent design and manufacturing, SST has swiftly built a large number of vacuum coating equipment and post-processing equipment, including MS, IBAD, PLD, slitting, copper-plating, lamination and so on. This production expansion targets to further reduce the fabrication cost and improve the performance of REBCO tapes, providing a consistent supply of high performance tapes for downstream applications. By the end of 2023, the SST’s annual REBCO supply has reached 2000 km/12 mm, and will be further expanded to 4000 km/12 mm in 2025. Along with the production expansion, SST also carries out researches extensively on tape customization and problem solving for specific application scenarios, covering laser slitting, stainless steel lamination, insulation coating, low resistance joints, continuous online thickness measurement techniques, and superconducting coil winding technologies, to help customers meet their technical requirements and achieve a successful project using SST's REBCO products. This paper will focus on the industrialization and R&D progress that SST has recently achieved.
