摘要
本文介绍了一种 HTS/LTS 混合偶极子的设计理念，该偶极子具有 50 mm 的孔径和 20 T 的额定磁场，基于一个 cos-theta 线圈和一个冷铁轭。LTS 部分是分级的，由两根 Nb3Sn 卢瑟福电缆组成。由于 HTS/LTS 线圈在高磁场下对大应力和应变非常敏感，因此采用了应力管理（SM）概念与 cos-theta 线圈几何形状相结合。本文介绍并讨论了磁体磁性分析的结果。
Conceptual Design of A 20 T Dipole Based on Hybrid REBCO/Nb3Sn Cos-theta Coil*
This paper presents a design concept of an HTS/LTS hybrid dipole with 50 mm
aperture and 20 T nominal field based on a cos-theta coil and a cold iron yoke.
The HTS part of magnet coil uses REBCO Twisted Stacked Tape cable. The LTS part
is graded and made of two Nb3Sn Rutherford cables. Due to high sensitivity of
HTS/LTS coils to large stresses and strains at high fields, a Stress Management
(SM) concept combined with the cos-theta coil geometry is used. The results of
magnet magnetic analysis are presented and discussed.
