ATLAS Collaboration

Do you want a career exploring the building blocks of the universe? ATLAS researchers share their top tips for becoming a particle physicist.

From elegant symmetries to iconic formulas, everyone has a favourite equation. What's yours?

Preparing for the High-Luminosity LHC, one box at a time! 📦 A key milestone has been reached by the ATLAS Experiment's Thin Gap Chamber (TGC) group, with all their components for the upcoming long shutdown of the LHC now delivered to CERN. The equipment includes the new TGC "frontend" electronics, produced at @KEK_JP in Japan. This will be the first muon system to be installed at the start of the shutdown, with installation planned to be completed within six months. A test bench has already been assembled using the newly delivered components — all set and ready to go! 📷️ C. Kawamoto & Y Yamaguchi #ATLAS #HiLumiLHC #CERN 

Registration is full! If you missed out, don't worry. We will be running more virtual zoom visits later this year. -- Join us for a rare look inside the ATLAS Experiment at CERN! ⚛️ Go 100 metres underground with ATLAS physicists Dr. Christian Appelt and Dr. Despoina Sampsonidou for an exclusive Open Virtual Visit. This is a unique opportunity to see the experiment up close before the cavern is closed for LHC operation. Learn about our latest research and get your questions answered live from the heart of the experiment. 📅 When: Thursday, 29 January at 5 pm CET / 11 am EST 📍 Where: Live on Zoom

What is the best part of working in physics? ATLAS physicists share what they love about their career and what makes it all worthwhile – in their native languages.

2025 was a breakthrough year for ATLAS! With record-breaking data-taking performance at the #LHC, new collision modes and major advances in preparations for the High-Luminosity LHC, the ATLAS Collaboration continued to push the boundaries of our understanding of the Universe.

Ever wondered what ATLAS physicists are working on? Same. We’ll let them explain!

Happy holidays from the ATLAS ITk workshop at CERN! The ATLAS Inner Tracker (ITk) is a major new detector currently under construction, upgrading ATLAS for the High-Luminosity LHC era. With the barrel frame decorated in seasonal lights and an electric tree nearby, the ITk team marked the season with a festive moment. ✨🔬🎄 #ATLASExperiment #CERN #ITk #HiLumiLHC #ParticlePhysics #HappyHolidays

How would you decorate a physics-themed Christmas tree? Our community has been getting creative with science-inspired decorations: - Custom baubles, highlighting real collision events and physics labs (here displayed at the recent VFSB workshop at @Fermilab) - Mini LEGO ATLAS detectors hanging inside clear ornaments - DIY particle decorations, coloured by young scientists to showcase fundamental building blocks (get your own here: https://lnkd.in/eScrGN-a) Have you ever created a science-themed tree in your lab, classroom or home? ⁠⁠ #ATLASExperiment #CERN #ParticlePhysics #STEMChristmas #ScienceOutreach

Physics is beautiful in every language. Don’t you think? Listen to ATLAS early-career physicists introduce themselves in their native languages – a great reminder of the global nature of the ATLAS Collaboration.
