High-Field Liquid-Neon-Cooled Electromagnets
Two large liquid-neon-cooled electromagnets using very high-purity aluminum as the conductor material have been fabricated, along with the necessary equipment for their operation, and the systems are in preliminary operational status. The 4½-in. bore colls of one electromagnet have already produced 200 kG, and when the 12-in. bore coils of the other are operated at the same current, they will produce over 150 kG, The coils were originally conceived as magnetic mirrors for plasma research. It now appears that high-field superconductors can fill that need, releasing the cryogenic colls for solid-state research and possibly biological experiments.
