About BL4S Competition

Take part in the BL4S Competition


Once again, in 2018, a fully equipped beam line will be made available at CERN for students from all around the world. As in previous years, two teams will be invited to CERN to carry out their proposed experiments. The competition is open to teams of high-school students who, if they win, are invited (with up to two supervisors) to CERN to run their experiment. Teams must have at least five students with at least one adult supervisor or "coach", but there is no upper limit to a team’s size (although just nine students per winning team will be invited to CERN). Teams may be composed of pupils from a single school, or a number of schools working together.

Are you interested about registering for edition 2018? 

Find out about the beamline and facilities on this website and go through the useful documents for details! Finally, think of a simple and creative experiment, submit your written proposal and your video before the deadline on 31st of March 2018.


Not sure if you should apply? Don’t be scared: a clever idea is all it takes to enter the competition. We can put every team in contact with experts that help them to refine their ideas and extensive documentation is available to both teachers and students.


One of the previous winning teams has studied the way limestone absorbs muons, using muon tomography, while the other team has tested the validity of the Special Relativity theory, using the decay rate of pions.

What would you want to do? Are you interested about the past editions and what the winning teams have done at the beam line? Check-out the "The Winners' proposals" on the video section and read more about the "Editions"!
