单层磁体:LTS和HTS基超导磁体的新概念

Uni-layer magnets: a new concept for LTS and HTS based superconducting magnets

José Luis Rudeiros Fernández, Paolo Ferracin

摘要:

本文提出了一种新的几何结构,即单层磁体,该结构利用非对称电流分布,利用连续的理想电流线,在单层磁体中形成垂直于孔的磁场。这个想法是比较现有的概念,在超导磁体,即,$\cosθ$部门磁铁,应力管理$\cosθ$和倾斜的$\cosθ$。单层磁体允许具有连续单位长度(无层跳跃)的设计,以及相对于传统的$\cosθ$和倾斜的$\cosθ$设计增加的导体的最小弯曲半径。单层设计的特定特性对于应变敏感且易于绕组退化的高温超导体在非常高的场加速器磁体应用中是特别有利的,其中需要导体的高使用效率和小孔径。还讨论了单层磁体的设计和制造相对于其他概念的优点。

英文摘要:

A novel geometrical configuration to form a magnetic field perpendicular to an aperture, created by an asymmetric current distribution, within a single layer, and using a continuous ideal current line, named the uni-layer magnet, is here presented. The idea is compared to existing concepts in superconducting magnets, namely, the $\cosθ$ sector magnet, stress managed $\cosθ$ and canted $\cosθ$. The uni-layer magnet allows for a design with a continuous unit length (no layer jump), and an increased minimum bending radius of the conductor in relation to traditional $\cosθ$ and canted $\cosθ$ designs. The specific characteristics of the uni-layer design are especially advantageous for strain-sensitive and prone to winding degradation high-temperature superconductors, in very high field accelerator magnet applications, in which, high efficiency in the use of conductor, and a small aperture are required. The advantages with regard to the design and fabrication of uni-layer magnets in relation to other concepts are also discussed.
