会切磁瓶探析—磁场位形为磁阱的新型磁约束装置

Exploration and Analysis of the Cusp Magnetic Bottle—New Magnetic Confinement Device with Configurations as Magnetic Trap

摘要: 会切磁瓶是由布置在正多面体各顶点的磁体，构成的磁约束装置。其内部的磁场位形，是底部磁感应强度为零的理想磁阱，已达到了阱深定义的极限值。磁感应强度变化曲线显示，在相同容积下，正12面体会切磁瓶的磁感应强度落差，是垒球缝线圈的磁感应强度落差的20多倍，且会切磁瓶还有着极大的可扩展性。会切磁瓶对等离子体的约束原理是依靠磁阱，磁约束理论表明，只有磁阱位形磁场，才能真正做到等离子体的稳定约束。而Tokamak或磁镜，是依靠磁力线对电粒子的粘连，理论和实践都表明，其存在着各种宏观和微观不稳定性。而在会切磁瓶中，这些不稳定性都将不复存在。从会切磁瓶的构成看，无论是材料、运行、扩展性等方面，会切磁瓶都有着传统磁约束装置不可比拟优势。

Abstract: The cusp magnetic bottle is a magnetic confinement device constituted by magnets on each vertex of the regular polyhedron. The internal magnetic field configuration is an ideal magnetic trap with the bottom magnetic induction intensity of zero, which could reach up to the limit value defined by the trap depth. The changing curve of magnetic induction intensity has indicated that, the magnetic induction intensity difference for cusp magnetic bottle of regular dodecahedron is over 20 times greater than that for softball seal coil of same volume and that the cusp magnetic bottle has a larger space to expand. The constraint theory of plasma by the cusp magnetic bottle is to rely on the magnetic trap and magnetic confinement theory indicates that, only magnetic trap configuration can truly achieve the stable confinement of plasma. Tokamak or magnetic mirror is to rely on the adhesion of particles of electricity on magnetic line of force. However, it has all kinds of macroscopic and microcosmic instabilities from both theoretically and practically. These instabilities would no long exist in the cusp magnetic bottle. From the constitution of cusp magnetic bottle, the materials, operation, structure, flexibility, expansibility and other aspects all indicate that the cusp magnetic bottle is far superior to traditional magnetic confinement devices.
