Abstract
The ability of large grain, REBa$_{2}$Cu$_{3}$O$_{7-\\delta}$ [(RE)BCO; RE =\nrare earth] bulk superconductors to trap magnetic field is determined by their\ncritical current. With high trapped fields, however, bulk samples are subject\nto a relatively large Lorentz force, and their performance is limited primarily\nby their tensile strength. Consequently, sample reinforcement is the key to\nperformance improvement in these technologically important materials. In this\nwork, we report a trapped field of 17.6 T, the largest reported to date, in a\nstack of two, silver-doped GdBCO superconducting bulk samples, each of diameter\n25 mm, fabricated by top-seeded melt growth (TSMG) and reinforced with\nshrink-fit…
