The competition invites teams of high-school students to propose a scientific experiment that they want to perform. Because of the maintenance of CERN's accelerators starting at the end of 2018, the winning experiments in 2019 will be run at DESY in Hamburg, Germany, a world-leading accelerator centre.

The first prize for the winning teams is a trip to DESY to carry out their proposed experiments at a fully-equipped accelerator beamline. There are additional prizes for shortlisted teams and certificates for all participants.

Take part in hands-on scientific experiments on-site at DESY, a world-leading research institute! Through BL4S, CERN and DESY offer a great opportunity for students to learn, make new discoveries and apply their knowledge into new settings. Get inspired by our videos and previous winners and stay tuned for news!

Pre-register now and submit your proposal until 31 March 2019!
