Beamline for Schools
Beamline for Schools (BL4S) is a physics competition for high school students from all around the world organised at CERN, the European Laboratory for Particle Physics, in Geneva, Switzerland, and DESY, the German Electron Synchrotron, in Hamburg, Germany. Teams of high school students can propose an experiment that they want to perform at a beamline, that is, a part of a particle accelerator. The teams that submit the three best proposals win a trip to CERN or DESY to perform their experiments at a fully-equipped beamline.
What is a beam and a beamline?
In particle physics, the term 'beam' refers to a large number of particles moving in the same direction. These particles can be accelerated to high energies. The term 'beamline' commonly refers to a straight section of a particle accelerator leading the particles to an experimental area.
Beamline for Schools 2024 - Happy 10th anniversary!
In 2024 two experiments will be performed at a beamline of CERN's Proton Synchrotron and one experiment will be performed at a beamline of the DESY-II synchrotron.
All participants who will submit an eligible proposal will receive a participation certificate. Additional prizes will be awarded to the shortlisted teams and the teams with the best video and outreach proposals, in total up to 40 teams.
