Reprocessing of imperfectly grown SDMG GdBCO/Ag bulks into top-grade stacks with predictable properties
Original language description
Top-Seeded Melt Growth (TSMG) is the most common used for manufacturing single-domain REBCO (rare-earth-barium-copper-oxide) bulks. However, growth defects often appear during the growth, leading to large amount of waste and defective bulks. Recently developed SDMG (Single-Direction Melt Growth) improves the production yield and properties of the grown bulks, nevertheless, a large number of defective bulks are still prepared, which tend to accumulate over time. To address this shortcoming, a method for stacking REBCO/Ag bulks grown by the SDMG technique was developed. SDMG-grown bulks with minor defects were characterized using 2D trapped field mapping. Based on the measured data, the positions and orientation of respective bulks within the stack were optimized and stacked using epoxy resin. The stacked bulk exhibited a highly circular trapped field, achieving a 0.92 T peak. This method demonstrates that imperfect single-domain superconductors can be effectively utilized. The process ensures high-quality superconducting materials, crucial for advanced technological applications, where a strong trapped field is required, such as energy storage systems and particle accelerators.
