Yesterday, we got exclusive access to the CMS facility!
It was a great chance for students to discover what’s behind the doors of CERN and learn more about the facilities they use. But don’t worry if you missed out, you can catch up below!
Watch the full tour:
Highlights of the Tour
17.17 – The underground gas room
This is where various gases are stored and mixed before sent into the detector for operation. Some gases are stored at around -40 degrees, so it’s pretty chilly down there!โ

20.55 – A retina scanner ๐
This is used as an extra layer of security to give special permission access to the experimental cavern. We thought this was very futuristic!

22.12 – Heart of the CMS detector
How does it work? The right hand part is called the end cap, which moves into the plug on the left when it’s running. It’s a huge machine at about 15 metres high, 20 metres long and has twice as much steel as the Eiffel tower! It was also heavily featured in the film Spiderman into the spider-verse!

Did you know? Inside the collider, 40 million proton collisions happen every second!๐ฅ
๐Take a look at what was discussed in the Chat below๐
