Another success for the HL-LHC magnet programme: after the successful endurance test of a 4.2-metre-long niobium–tin quadrupole magnet in the United States in spring 2022, the HL-LHC quadrupole’s long...
Much of the research and development work for the High-Luminosity LHC (HL-LHC) aims to protect the accelerator’s fragile components from the detrimental effects of high luminosity, such as radiation a...
When the Large Hadron Collider (LHC) is operating, it produces more than one billion proton–proton interactions every second. But exactly how many take place in the LHC experiments? Critical to every ...
At the scale of individual atoms, physics gets weird. Researchers are working to reveal, harness, and control these strange quantum effects using quantum analog simulators — laboratory experiments tha...

英国曼彻斯特大学表示，部分在英国曼彻斯特建造的新型顶点定位器（Vertex Locator）的成功实施，使大型强子对撞机（LHC，欧洲核子研究组织的对撞型粒子加速器）自三年翻新以来首次成功接近质子碰撞点。
After over three years of upgrade and maintenance work, the Large Hadron Collider began its third period of operation (Run 3) in July 2022. Since then, the world’s most powerful particle accelerator h...
Ivan Bazarov, professor of physics, has received a $410,000 grant from the Office of Nuclear Physics at the Department of Energy for research on long lifetime spin-polarized electron sources in partic...
The SM18 test facility, located in France, near the Meyrin site, was originally built to test and validate the magnets and radiofrequency (RF) cavities of LEP (the Large Electron–Positron Collider). I...
Hypothetical particles called axions could solve two enigmas at once. They could account for dark matter, the mysterious substance that is thought to make up most of the matter in the Universe, and th...
For the first time, researchers at MIT, Caltech, Harvard University, and elsewhere sent quantum information across a quantum system in what could be understood as traversing a wormhole. Though this ex...
