Display of a collision event recorded by ATLAS on 5 July 2022, when stable beams of protons at the energy of 6.8 TeV were delivered to ATLAS for the start of #LHCRun3.
Display of a collision event recorded by CMS on 5 July 2022, when the collisions at the record energy of 13.6 trillion-electronvolts (TeV) were first recorded by the #LHC experiments. #LHCRun3
Display of a collision event recorded by ALICE on 5 July 2022. After three years of preparation, #physics data-taking begins with a fully upgraded ALICE detector.
Today’s #PhotoOfTheWeek is all about the @LHCbExperiment. We are almost ready for #restartingLHC, so here are some of the tasks involved in the upgrade of the LHCb experiment. 💪
@LHCbExperiment ✅ Upgrade of the VErtex LOcator, a detector used to determine the exact point where the particles collide. One of its sensors is just 5mm away from the beam. Brand new modules were installed, with 40 million active pixels.
@LHCbExperiment ✅ New mirrors for the ring-imaging Cherenkov (RICH) detectors: this system consists of two huge digital cameras that measure the speed of particles. The lens system of the cameras is made of about 200 flat and spherical mirrors immersed in special gases.
“I would like to express my deepest gratitude to the many partners in our Member and Associate Member States and beyond who are making the #CERNScienceGateway possible, in particular to our generous donors.”
Fabiola Gianotti, CERN Director-General
“We will do our best, not only in the construction & operation of the #CERNScienceGateway but also more widely to ensure that science maintains a place of integrity and trustworthiness, of international collaboration aiming for peace”
Ursula Bassler, President of the CERN Council

#DidYouKnow that Silicon-based detectors similar to this one are widely used in high-energy physics experiments?
The #Medipix collaboration makes the technology behind silicon pixel detectors available for applied physics domains such as medical imaging. medipix.web.cern.ch
Do you like cold summer drinks? 🍹🏖
Today, we show you how to use supercool thermodynamics to create your own cryogenic system in your kitchen.
#Bubblechambers are able to produce fascinating visualisations of particle tracks, but are no longer used @CERN. Therefore, why not get creative & share your homemade #bubblechamber#kitchenart
What is a period of restlessness for many of us can be turned into a time of reflection and learning from the safety of our homes. What better way to do that than with a healthy diet of physics-themed videos? 1/n #StayAtHome
Let's start with John Ellis. We thought it's time to finally figure out what the Higgs boson is... 2/n #StayAtHome
Watch the unlikely story of our most venerable accelerator, from the mouth of our most venerable coworkers ⤵️
The #CERNOpenDays have officially started! CERN’s Director-General Fabiola Gianotti opened the Laboratory’s doors at a ceremony attended by representatives of the local authorities.
Welcome to the #CERNOpenDays! Get ready to explore the future with us 🖖
