欧洲核子研究组织（CERN）已启动大型强子对撞机（LHC）的重大升级工程，开始拆卸并替换该设备内的28个超导磁体1。这项工作作为高亮度升级项目的一部分，在第三长期停机期间进行，自9月7日起启动1。
新的超导磁体将大幅增强装置性能1。其产生的磁场强度达到11.3特斯拉，较现有磁体提高约40%1。更强的磁场将使粒子束在碰撞前被压缩得更紧，为ATLAS和CMS实验产生远更多的碰撞数据1，帮助物理学家深入了解宇宙基本运作原理1。
升级工程涉及大规模设备更新1。此次将总共安装16个低温罐和28个低温组件1，其中第一个新的三联组四极磁体预计在2029年初到达隧道1。现有磁体自2005年至2007年间安装，已运行近20年1，ATLAS和CMS实验所在位置将被优先安装新设备1。
The European Organization for Nuclear Research (CERN) has initiated the replacement of critical magnets in the Large Hadron Collider as part of its High-Luminosity upgrade project 1. A total of 28 superconducting magnets will be removed and replaced with new units capable of generating magnetic fields approximately 40% stronger than the existing system 1. The new magnets will produce magnetic field strengths of 11.3 Tesla, enabling tighter compression of particle beams before collision and significantly increasing collision data for the ATLAS and CMS experiments 1.
This overhaul commenced during the third long-term shutdown (LS3), which began on September 7 1. The first new triplet quadrupole magnet is expected to arrive at the tunnel in early 2029 1. Installation of the new equipment will prioritize locations at the ATLAS and CMS detector sites 1. The existing magnets, which have been in operation for nearly two decades since their installation between 2005 and 2007, will be systematically removed to make way for the enhanced system 1.
