位於法瑞邊境深處的世界上最大型的科學儀器大型強子對撞機 (LHC) 已停止運行並進入了長時間的停機狀態。經過多年以接近光速的速度將質子粒子進行對撞之後，Cern 的大型強子對撞機已經停止了操作。雖然目前在大型強子對撞機沒有發生任何粒子碰撞，但數以千計的科學家、工程師和技術人員正在拆卸該機器的部件、安裝新技術，並為實驗物理學史上最雄心勃勃的升級之一做準備。

當它在大約 2030 年再次開啟時，它將成為高亮度大型強子對撞機 (HL-LHC)，能夠提供大約是發現了希格斯玻色子的對撞機 7 倍之多的數據。對於我來說，這次停機標誌著一個已經塑造了我大部分科學生活之項目的另一個里程碑。遠在 2012 年希格斯玻色子粒子被發現之前，我就首次參與了高亮度對撞機的項目。在將近二十年的時間裡，我有幸在大西洋兩岸為該項目做出了貢獻。

在美國，我曾擔任緊湊渺子線圈 (CMS) 的升級協調員。這項正在進行中的升級將帶來前所未有的數據收集能力，為物理學的未來發現鋪平道路。

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.
