International competition for high school students from all around the world organised by CERN, the European Organization for Nuclear Research, in Geneva, Switzerland
The competition invites teams of high-school students to propose a scientific experiment that they want to perform at a particle accelerator. The two teams that prepare the best proposals will win a trip to a particle accelerator facility to perform their experiments at a fully-equipped beamline. Because of the maintenance of CERN's accelerators since the end of 2018, the winning experiments in 2021 will run at DESY in Hamburg, Germany. There are additional prizes for a shortlist of teams and certificates for all participants. Learn more about BL4S and how to apply
