#ThrowbackThursday to the summer of 1982 🧑‍🏫. Here we see physicist John Bell, known for his theorem on the foundations of quantum mechanics – which he worked on #AtCERN – laying the groundwork for the now-vibrant field of quantum information. On the blackboard we see entangled

Oxygen and neon collisions at the LHC for the first time ever 🚀. On 1 July, the four large #LHC experiments recorded particle collisions between oxygen and proton beams for the first time ever. Last week, they went a step further with oxygen-oxygen and neon-neon collisions.

Here we see engineers working on the High-Luminosity LHC Inner–Triplet (IT) String test stand. The #HiLumiLHC will be the successor to CERN’s Large Hadron Collider, due to start in early 2030. It aims to increase the number of particle collisions (luminosity) and so boost the

From relay races, games, and movie nights to shared laughs over lunch breaks and sports or creative clubs, today’s #PhotoOfTheWeek illustrates how community and collaboration thrive at CERN beyond (and for the benefit of) fundamental science research.

A glimpse of life #AtCERN 💫. Beyond accelerating particles and exploring the mysteries of our Universe, CERN also offers an active social programme.

#ThrowbackThursday to March 1976 🪞. Here we see the assembly of the lead counter for the OMEGA experiment, a large detector capable of studying a wide range of particle interactions. That year, OMEGA was adapted for the Super Proton Synchrotron program and studies focused on

Today's #PhotoOfTheWeek features AMS-02, a magnetic spectrometer for particle physics that has been operating on the International Space Station since 2011. Built to study dark matter, #antimatter, and the origins of the Universe, it is about to receive a major upgrade to dig

Here we see the first Beam Position Monitors (BPM) produced in CERN’s workshops for the #HiLumiLHC, the successor to the Large Hadron Collider. The BPM is a device that measures the position of the particle beam in the accelerator in a non-intrusive way. It uses four pick-up
