15.08.2024 – The CERN control room – please do not speak to the driver during operations !
Entering the Monster !
You are here.
Don’t mix the pipes !
Never mix gaz and electricity…
This is NOT a microwave

16.08.2024 – My Geiger counter, healthy on the parking, before the visit.
On the 16.08.2024, I don’t know why, but the group made a very different visit… We have been guided to an alternative path… The so-called:
16.08.2024 – Welcome to a brand new world !
The mysteries of antimatter
We were warned !
Who wants to try first ?
Once inside, we were informed that anything may happen in this area, as we are at the edge of human science knowledge…
If you still want to follow, you’re welcome.
Those are the so-called “hazardous areas” !
16.08.2024 – My Geiger counter was very exited also ! I never saw him so high… on Earth !
The idea of this factory is nothing else than making and experiencing antimatter !
Here, they throw particles on a target of whatever usefulness matter (such as a mother-in-law dead body) and collect the results. It is then sorted depending on its mass and electric charge.
The so obtained positrons (anti-electrons) are carefully slowed down by various methods and stored in presence of anti-protons.
At the other side, they make antiprotons.
Antiprotons are presented to the positrons. Some find a match and form an anti-hydrogen atom.
As there is almost NO WAYS to observe antimatter, the first question is: does antimatter obey gravitation the usual way or the opposite way ?
This is where it happens. Atoms of antihydrogen “last” in average half an hour, as they annihilates as soon as they meet “real” matter. When they do so, ~80% of them are BELOW the level they were “born”, and only 20% above, so the gravity is (so far) supposed to be followed the usual way by antimatter.
And there is a full bench of other crazy experiences on their way around antimatter in this building.
That is how knowledge progresses !
If you are looking for antihydrogen to refill your electric car, it’s stored at the back of the factory. But don’t complain if your next stop is at the opposite of the galaxy !

Visit of the Datacentre
The HLC runs almost all the time and produces hundreds millions of collisionseach second, leading to 50+ disintegrations each time. The amount of data produced is hundreds of times higher than what the current state-of-the-art technology is able to store and process…
Data is first sorted electronically. One percent is kept for software filtering. Part of it is then stored and processed through a world-wide area of Tier-1 datacentres, belonging to CERN partners.
Data storage technologies evolved since the early 60’s but are still based on magnetic media. Old data are kept and copied to newer storage generation devices. And yes, there is a backup !
CERN exceptional IT needs contributed to the creation of the HTML (Hypertext Markup Language) standard, leading to the well-known World Wide Web.
Still today, I.C.T. techniques are driven forward by the exceptional needs of CERN and more widely, science and knowledge progress.
This very hardware has been the second CERN web server (the first one is in a museum)
