Commonwealth Fusion Systems (CFS) is building the world’s first compact net energy fusion device, SPARC, by utilizing recent advances in the commercial production of 2G REBCO coated conductors. SPARC’s delivery and operation will inform the design of ARC, the world’s first fusion power plant, scheduled to come online in the early 2030s. The design, safe operation, and quench protection of high field fusion magnets requires the detailed characterization of the field (B), angle (Θ), and temperature (T) dependence of the critical current (Ic) of these tapes at the operational range for each magnet system, nominally 20K, 20T. User facilities for characterizing HTS at very high fields are limited, and measurement standards do not currently exist. Additionally, the high volume of HTS tape needed for SPARC is on the order of 10,000 km, requiring CFS to develop a statistical process approach for quality assurance testing of received tape. This talk will summarize the present and future requirements needed for REBCO coated conductors to make use of them in high field fusion magnets and outline the development and validation of the methods used for HTS testing at CFS including comparing the results of predicted vs measured performance of large R&D magnet tests at CFS including TFMC and CSMC.
