About BL4S Competition

Beamline for Schools – Be a scientist


Did you ever wonder what it is like to be a scientist? If you’re up for a challenge, the BL4S competition is your chance to experience it. Any high-school students from all around the world can join the adventure.

Jump into the world of particle physics and think of a simple and creative experiment. You are not alone, if you need assistance, our contacts can support you. Don't miss it and take part in this once-in-a-lifetime opportunity!


The competition is open to teams of high-school students who, if they win, are invited (with up to two supervisors) to DESY 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 DESY). Teams may be composed of pupils from a single school, or a number of schools working together.

Find out more about the competition by checking out our website. 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.


Take part in this once-in-a-lifetime opportunity!
