摘要

电子离子对撞机（EIC）将碰撞高能和高极化强子和电子束，其亮度高达1034 cm−2s−1。由于强子和电子束的接近，在相互作用区（IR）的磁体设计具有挑战性。由于红外空间的限制，设计了斜余弦（CCT）四极磁体。CCT磁体具有锥形孔径，这使得磁体的相互作用点（IP）侧具有更高的梯度。锥形的几何形状使磁体沿轴向不对称。为了验证设计的机械强度和允许的变形，考虑冷却收缩和导体上的电磁力，采用有限元法对锥形CCT四极磁体进行了详细的结构力学分析。

Structural Analysis of Multilayer Tapered Canted-Cosine-Theta Superconducting Magnet for the Interaction Region of Electron Ion Collider

The electron ion collider (EIC) will collide high energy and highly polarized hadron and electron beams with luminosities up to 10³⁴ cm⁻²s⁻¹. The magnet designs at the interaction region (IR) are challenging due to the close proximity of the hadron and electron beams. A canted cosine theta (CCT) quadrupole magnet was designed due to the space restrictions at the IR. The CCT magnet has a tapered aperture, which allows higher gradients at the interaction point (IP) side of the magnet. The tapered geometry makes the magnet not symmetrical along the axial direction. To validate the design in terms of the mechanical strength and the allowed deformations, a detailed structural mechanical analysis for the tapered CCT quadrupole magnet has been carried out using the finite element method (FEM) considering both the shrinking due to cool down and the electromagnetic force on the conductors.
