Would you like to perform your own experiment? Here’s what you need to know: Register: cern.ch/bl4s Proposal submission deadline: 13 March Additional prizes for up to 70 teams Beamline for Schools is supported through the CERN & Society Foundation.

Students from all around the world propose an experiment to be conducted at a beamline, and the teams with the best proposals will win a trip to CERN, Deutsches Elektronen-Synchrotron DESY, or Electron Stretcher Facility ELSA to conduct their experiments.

Only one more month to apply 📣 Beamline for Schools (#BL4S) is a physics competition for high-school students worldwide. Hear from last year’s winning teams about their experience.

Last week we asked you to guess what this was… 🔎 Here we see the Experimental Linac for Surface Analysis (ELISA), a compact proton accelerator built for exhibition in #CERNScienceGateway – the only one that is ready for demonstrations to the public.

Beamline for Schools is supported by donors and partners through the CERN & Society Foundation. The Foundation connects CERN’s science, creativity, and innovation with society.

Teams can participate in preparatory online events and virtual visits before submitting their proposal. Submit your experiment proposals by 13 March 2026. Learn more and apply: cern.ch/bl4s
