If you are a high-school student with an idea for a #physics experiment to conduct at a particle accelerator, submit your proposal to win the chance to spend two weeks at CERN, Deutsches Elektronen-Synchrotron DESY or Electron Stretcher Facility ELSA to perform your experiment.

📣 Pre-registration for Beamline for Schools (#BL4S) is open. Beamline for Schools (#BL4S) is a #physics competition open to high-school students from all over the world.

Are you a high school teacher or university professor eager to guide a team of 5–9 students in designing an experiment at #CERN, #DESY, or #ELSA? Pre-register for the Beamline for Schools Competition and discover how to take part. Proposal submissions will open in January 2026. cern.ch/bl4s

Yesterday, someone walked into my office and asked me where I was from. When I told him I was from Colombia, he immediately said, “Ohhh, that’s why you’re so kind!” Such a simple comment, but it absolutely made my day. 😄
