“Places like CERN give us hope for a better world. Places like CERN show what humanity can achieve when we set aside our disputes and focus on the common good.”

« Des institutions comme le CERN donnent l'espoir d'un monde meilleur, et montrent ce que l'humanité peut accomplir lorsqu’elle met ses différends de côté et agit pour le bien commun. »

#CERN70

Earlier today, I had the privilege of visiting CERN’s Large Hadron Collider. Walking through those halls, I was awestruck by the scale of the groundbreaking experiments happening here. Meeting the Belgian scientists involved in this remarkable work was truly inspiring. Belgium is proud to support CERN and I reaffirm our commitment to this exceptional European collaborative research project. Here’s to 70 years of discovery and to many more years of adventure driven by the CERN community’s human curiosity.

#CERN70

No European country alone could have built the world’s largest particle collider. CERN has become a global hub because it rallied Europe and this is even more crucial today. I am proud that we have financed the feasibility study for CERN’s Future Circular Collider (FCC). This could preserve Europe's scientific edge and could push the boundaries of human knowledge even further. And as the global science race is on, I want Europe to switch gears. To do so, European unity is our greatest asset.

@NobelPrize

#OnThisDay in 1902, the theoretical physicist Paul Dirac was born.

As we #FollowTheProtons to CERN’s #Antimatter Factory, what better way to start than by celebrating the work of this young physicist and his @NobelPrize-winning equation?

@NobelPrize

@NobelPrize In 1928, Dirac wrote an equation to describe the behaviour of an electron moving at a relativistic speed. It could have two solutions: one for an electron with positive energy, and one for an electron with negative energy.

@NobelPrize

@NobelPrize This equation, in some way, predicted for the first time the existence of an anti-world identical to ours, but made out of antimatter.

What would you ask him about antimatter if you could meet him? 🎂

@ATLASexperiment

The first collisions of #LHCRun3 🤩

In this #PhotoOfTheWeek, take a look at the first high-energy collisions recorded by the LHC's @ATLASexperiment, @CMSExperiment, @ALICEexperiment and @LHCbExperiment, as well as other experiments, such as @FASERexperiment and SND. 👇

@ATLASexperiment

A Toroidal LHC Apparatus (ATLAS) @ATLASexperiment

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.

@CMSExperiment

Compact Muon Solenoid (CMS) @CMSExperiment

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

@LHCbExperiment

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

@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

@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.
