在悬浮偶极实验 (LDX) 中，在直径 5 m 的真空容器中心的悬浮超导偶极磁体周围形成热等离子体。在八小时的实验运行过程中，悬浮磁铁被磁力悬浮，然后降低并重新冷却过夜。浮动 F 线圈磁体由 4 个部分的层绕磁体组成，旨在将磁通线紧密包裹在悬浮低温恒温器的外部。导体是铌锡卢瑟福电缆，具有足够的稳定剂以实现被动失超保护。铅条用作热电容器以减缓线圈加热。优化的缓冲器和冷质量支撑系统减少了泄漏到氦容器中的热量。气囊在淬火和故障时捕获浮动线圈，防止与真空容器碰撞。
In the Levitated Dipole Experiment (LDX), a hot plasma is formed about a levitating superconducting dipole magnet in the center of a 5 m diameter vacuum vessel. The levitated magnet is suspended magnetically during an eight hour experimental run, then lowered and recooled overnight. The floating F-coil magnet consists of a layer-wound magnet with 4 sections, designed to wrap flux lines closely about the outside of the levitated cryostat. The conductor is a niobium-tin Rutherford cable, with enough stabilizer to permit passive quench protection. Lead strips are used as thermal capacitors to slow coil heating. An optimized system of bumpers and cold-mass supports reduces heat leak into the helium vessel. Airbags catch the floating coil on quenches and faults, preventing collision with the vacuum vessel.
