位于法瑞边境深处的世界上最大型的科学仪器大型强子对撞机 (LHC) 已停止运行并进入了长时间的停机状态。经过多年以接近光速的速度将质子粒子进行对撞之后，Cern 的大型强子对撞机已经停止了操作。虽然目前在大型强子对撞机没有发生任何粒子碰撞，但数以千计的科学家、工程师和技术人员正在拆卸该机器的部件、安装新技术，并为实验物理学史上最雄心勃勃的升级之一做准备。

当它在大约 2030 年再次开启时，它将成为高亮度大型强子对撞机 (HL-LHC)，能够提供大约是发现了希格斯玻色子的对撞机 7 倍之多的数据。对于我来说，这次停机标志著一个已经塑造了我大部分科学生活之项目的另一个里程碑。远在 2012 年希格斯玻色子粒子被发现之前，我就首次参与了高亮度对撞机的项目。在将近二十年的时间里，我有幸在大西洋两岸为该项目做出了贡献。

在美国，我曾担任紧凑渺子线圈 (CMS) 的升级协调员。这项正在进行中的升级将带来前所未有的数据收集能力，为物理学的未来发现铺平道路。

Deep beneath the French-Swiss border, the world’s largest scientific instrument, the Large Hadron Collider (LHC), has halted operations and entered a prolonged shutdown. After years of colliding proton particles at near-light speeds, Cern’s LHC has ceased its activities. Although no particle collisions are currently taking place at the LHC, thousands of scientists, engineers, and technicians are dismantling parts of the machine, installing new technologies, and preparing for one of the most ambitious upgrades in the history of experimental physics.

Upon its reactivation around 2030, it will transition into the High-Luminosity Large Hadron Collider (HL-LHC), with the capacity to deliver approximately 7 times more data than the collider that uncovered the Higgs boson. For me, this shutdown represents another milestone in a project that has defined much of my scientific career. I first engaged with the High-Luminosity collider project long before the discovery of the Higgs boson particle in 2012. Over nearly two decades, I have been privileged to contribute to the program on both sides of the Atlantic.

In the United States, I functioned as the upgrade coordinator for the Compact Muon Solenoid (CMS). This ongoing upgrade will yield unprecedented data collection capabilities, paving the way for future discoveries in physics.
