Abstract

A conceptual design for cooling superconducting accelerator magnets operating at 4.5 K is proposed for the hadron-hadron configuration of the Future Circular Collider (FCC-hh). This is motivated by efforts to reduce helium inventory and energy costs, while ensuring compatibility with the tunnel structure envisaged for FCC-ee, and providing a technically viable solution for the magnets. The study is carried out for the latest configuration of the FCC-hh machine, the so-called F14 scenario, that uses Nb

$_{3}$

Sn superconducting magnets with an operational magnetic field of 14 T, for a centre-of-mass energy of 85 TeV with a magnetic filling scheme of 83%. The updated heat loads are presented, along with expected longitudinal and radial temperature gradients in the magnet structure. The move from 1.9 K operation, which makes extensive use of He II, towards 4.5 K using single-phase helium significantly reduces the overall cryogenic power consumption by 30%, and the machine’s helium inventory by 50%.

欧洲核子研究中心FCC-hh加速器4.5 K低氦含量低温冷却方案

提出了一种用于未来圆形对撞机（FCC-hh）强子-强子配置的4.5 K超导加速器磁体冷却的概念设计。这是为了减少氦气库存和能源成本，同时确保与FCC-ee设想的隧道结构的兼容性，并为磁体提供技术上可行的解决方案。这项研究是针对FCC-hh机器的最新配置进行的，即所谓的F14方案，该方案使用Nb$_{3}$Sn超导磁体，工作磁场为14 T，质心能量为85 TeV，磁填充方案为83%。给出了更新后的热负荷，以及磁铁结构中预期的纵向和径向温度梯度。从广泛使用He II的1.9 K操作转向使用单相氦气的4.5 K操作，显着降低了30%的整体低温功耗，机器的氦气库存降低了50%。
