Abstract

To further explore the physics beyond the capabilities of the LHC and its High-Luminosity Upgrade (HL-LHC), particle physicists are studying advanced accelerators in order to perform finer measurements and/or reach higher energies. Upon the recommendation of the Updated European Strategy for Particle Physics (ESPP), an International Muon Collider Collaboration has been established to investigate the feasibility of a muon collider facility with a center-of-mass energy of 10 TeV. This endeavor is confronted with several technical challenges, primarily arising from the brief muon lifetime at rest, which is only 2.2 ${\mu }$ s. Addressing this stringent constraint necessitates the deployment of innovative technologies, including challengingmagnets, RF systems, targets, shielding, and cooling methodologies. This paper focuses on optimizing the electromagnetic and mechanical aspects of high-temperature superconducting (HTS) dipoles with large rectangular aperture for the accelerator ring, with a bore field up to 10 T, using finite element techniques. The objectives include ensuring a precise control over magnetic field uniformity and a preliminary evaluation of the mechanical behaviour of the HTS coils. The study is aligned with the priority set by ESPP on technological advancements, notably in high-field superconducting magnets, crucial components for any forthcoming circular collider.

介子对撞机加速器环用大孔径高温超导偶极子的磁性和机械设计
为了进一步探索LHC及其高亮度升级(HL-LHC)能力之外的物理,粒子物理学家正在研究先进的加速器,以便进行更精细的测量和/或达到更高的能量。根据欧洲粒子物理更新战略(ESPP)的建议,建立了一个国际μ子对撞机合作组织,以研究一个质心能量为10 TeV的μ子对撞机设施的可行性。这一努力面临着几个技术挑战,主要是由于静止的μ子寿命很短,只有2.2 ${\mu}$s。解决这一严格的限制需要部署创新技术,包括具有挑战性的磁铁,射频系统,目标,屏蔽和冷却方法。本文重点研究了利用有限元技术对直径达10t的加速器环用大矩形孔径高温超导偶极子的电磁和力学性能进行优化。目标包括确保对磁场均匀性的精确控制和对高温超导线圈的机械行为的初步评估。这项研究符合ESPP对技术进步的优先考虑,特别是在高场超导磁体方面,这是任何即将到来的圆形对撞机的关键部件。
