After the spectacular success of Beamline for Schools 2020, the competition is back again for its eighth edition!  This physics competition offers high-school students the unique opportunity to carry out an experiment at CERN or in a partner research laboratory. Beamline for Schools has become increasingly popular over the past seven years, with more than 11000 students from around the world having taken part.

Each year, two of the teams that compete are selected by a committee of experts to conduct their experiments at a particle physics facility. In 2021, the CERN test-beam area will still be under scheduled maintenance and so cannot host experiments. The experiments will thus be performed at DESY in Hamburg, Germany. DESY is a world-leading accelerator centre and Germany's national laboratory for particle physics, accelerators and photon science. It offers particle beams and infrastructure where a very wide range of experiments in particle physics, detector development and multidisciplinary science can be conducted.

The registrations for the 2021 process is now open and is quite simple:
