CERN Guided Tours

CERN Guided Tours

If you come early or leave late from the conference you will have the opportunity to visit part of CERN, the world's largest physics laboratory where more than 15000 researchers from 100 nations work together to try and answer the most fundamental questions of the universe.

You can indicate whether you want to participate in a guided tour to CERN at the registration form. Due to capacity and because we want to give this opportunity to as many of you as possible, you will have to decide for one of three different tours which are presented here:

Synchrocyclotron & ATLAS Visitor Center

Possible Slots: Monday (15/09), 11:00-12:30; Wednesday (17/09), 18:00-19:30

In this combined tour you will have the opportunity to visit CERN's first particle accelerator, the Synchrocyclotron (SC), having been in operation between 1957 and 1990 and now serving as a unique experience which takes visitors back in time to find out about the origins of CERN while also learning about the basic principles of particle acceleration.

In addition to that, you will have the opportunity to learn about the largest particle detector at CERN, the ATLAS detector. Find out what a particle detector does (spoiler: it detects particles), why we need them, how they work, and what we have discovered with them.

Antimatter Factory

Possible Slots: Monday (15/09), 10:30-11:40 and 11:20-12:30; Wednesday (17/09), 18:00-19:10

In this tour you will visit a very special place: the only place in the universe where antimatter is created. In some sense, this research facility takes us back to a time, seconds after the big bang, when the universe still consisted of roughly equal amounts of matter and anti-matter. However, there was a tiny difference between these amounts. And this difference is the reason why not all the matter in the universe was "cancelled out" by anti-matter. To this day, we have no clue what this tiny difference between matter and anti-matter is. And as long as we don't know this, we cannot answer one of the most fundamental questions of humankind : Why are we here? 

If you want to find out how researchers at CERN try to answer this fundamental question, and if you want to see an operational particle accelerator, sign up for this tour.

Careful: This tour is not possible if you are pregnant, and please note that it involves stairs.

Data Center

Possible Slots: Monday (15/09), 10:30-11:40 and 11:20-12:30; Wednesday (17/09), 18:00-19:10

In the experiments at the Large Hadron Collider (LHC), the largest and most powerful accelerator in the world, particles collide at a mind-boggling rate of 40 million collisions per second. And each of these collisions provides precious data about the mysteries of our universe. But how do we process and store data at this insane rate (for comparison: the amount of data produced by the LHC experiments in one second is in the same order of magnitude as the amount of data uploaded to YouTube in one day)? And where does that happen?

To find out about all of this and to see a real, operational data centre, sign up for this tour.
