本文介绍了几种磁性设计的16 T 50毫米口径Nb3Sn偶极子的基础上，共同的线圈设计的未来圆形对撞机。它的孔径间距为250 mm，磁轭外径为700 mm，并且使用与余弦θ或块设计相似或更少的导体量。在整个运行范围内，所有场谐波的数量级均优于设计场规定的数量级，且远低于规范。机械设计和分析的初步结果也令人鼓舞。它们表明，所提出的结构能够支撑磁极线圈块抵抗垂直洛伦兹力，并且所有线圈中的最大应力通常保持在150 MPa以下。考虑到共同线圈设计的几个固有优点，这里提出的发展应该使这种方法成为未来对撞机中非常高场磁体的主要候选者。
This paper presents several magnetic designs for a 16-T 50-mm aperture Nb3Sn dipole based on the common coil design for a future circular collider. It has an aperture-to-aperture spacing of 250 mm, a yoke outer diameter of 700 mm, and uses a similar or less conductor amounts than cosine theta or block designs. All field harmonics are about an order of magnitude better than specified at the design field and well below the specification in the entire range of operation. Initial results of mechanical design and analysis are also encouraging. They indicate that the proposed structure is able to support the pole coil blocks against the vertical Lorentz forces and that the maximum stresses in all coils remain generally below 150 MPa. Given several inherent advantages of the common coil design, the development presented here should make this approach a leading candidate for very high field magnets in future colliders.
