我们已经开发了一个致密的，超临界氦冷却超导体的分析模型，稳定到可以承受短期的不稳定性。该模型考虑了电流共享过程中瞬态不稳定性和焦耳加热产生的能量吸收。根据几何形状和超导体临界温度对冷却剂传热参数进行了优化。数据显示了一种新的扩展表面导体束的优点。这项工作针对的是5到9特斯拉范围内的大型高磁场磁铁。提出了小直径6米的环形“托卡马克”线圈和长10米×直径2.5米的鞍绕“MHD”磁体的概念设计。
We have developed an analytical model of a dense, supercritical helium-cooled superconductor, stabilized to withstand short-term instabilities. The model allows for the absorption of energy from transient instabilities and Joule heating during current sharing. Coolant heat transfer parameters are optimized with respect to geometry and superconductor critical temperatures. Data is presented to demonstrate the advantages of a novel extended surface conductor bundle. This work has been directed at large, high-field magnets in the 5 to 9 Tesla range. Conceptual designs of a toroidal "Tokamak" coil of 6 meter minor diameter and a 10 m. long × 2.5 m. diameter saddle-wound "MHD" magnet are presented.
