Abstract Scope |
Several projects have been initiated on compact fusion based on superconducting magnets that operate in ultra-high magnetic fields. The enabling technology for these magnets is RE-Ba-Cu-O (REBCO, RE=rare-earth) superconductor tapes. While REBCO superconductors are being manufactured for prototype compact fusion systems, significant cost reduction is needed for future full-scale systems. Our goal is to reduce the cost to $10/kA-m by increasing the critical current at 20K, 20T by 10x and reducing the unit cost 3x. Our approach is through an advanced metal organic chemical vapor deposition (MOCVD) process developed at the University of Houston. This process has been used to fabricate REBCO tapes with 5 µm thick films which is not feasible by conventional processes. Additionally, through nanoscale defect engineering, we have demonstrated critical current 5x than that of commercial tapes in high magnetic fields at low temperatures. Recent progress in this project will be discussed in this presentation. |
