Ever dreamed about 3D-printing your very own laser lab? Now you can! Print yours today and start exploring core ideas of special relativity, general relativity and quantum physics: cern.ch/laserlab3D
Think piezo speakers are no good? There’s no better way to displace a mirror on a nanometre scale. 😊 Grab your 3D-printed laser lab and start measuring signals like those you’d find in gravitational-wave detectors. #LIGO
#DidYouKnow lasers are colour-tuned to excite atoms produced at ISOLDE, CERN’s radioactive beam facility. The lasers remove an electron from the atom, turning it into an ion. This is the role of the element-selective ion source called RILIS: rilis.web.cern.ch

“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. »

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.

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.

#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 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 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? 🎂
On 13 July, CELESTA was launched into #space aboard #VegaC.
Here are the quick facts:
🛰️ It is the first CERN-driven satellite
🤖 It will study radiation's effects on electronics
🤝🏽 It is a collaboration with @umontpellier
Protecting satellites against radiation is a challenging and costly task. Some of CERN’s facilities are able to reproduce the environment of Earth’s orbit at a low cost, and help with radiation testing: kt.cern/aerospace/faci…
To study the effect of space radiation on electronics, CERN has developed a radiation monitoring device, Space RadMon, taken into space with the #CELESTA microsatellite aboard #VegaC.
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
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
