For the development of compact fusion reactors and other applications, there is a growing demand for REBCO HTS tapes with high critical current (Ic) at low temperature and high magnetic field. While focusing on expanding our manufacturing capabilities, SuperPower is continuously working not only to enhance its in-filed Ic but also to improve length-wise in-field Ic uniformity, the uniformity of its geometric dimensions uniformity, and the reduction of variability between lots. In this presentation, overview of our recent progress will be presented.
