From 10 to 24 September, CERN, DESY (the German electron synchrotron facility) and University of Bonn welcomed the winners of the 2025 Beamline for Schools (BL4S) competition.

Beamline for Schools is an education and outreach project funded through the CERN & Society Foundation that started in 2014 in the context of CERN’s 60th anniversary. In this competition, multiple teams of high-school students propose an experiment to be performed on a beamline – an experience designed to inspire the scientists of tomorrow to continue their careers in STEM (science, technology, engineering and maths). The winning teams have the opportunity to run their experiment like true physicists, immersed in a cutting-edge physics environment in one of the three laboratories.

This year, high-school students from Belgium, Türkiye, Canada, Mexico and the United States carried out their own experiments using accelerator beams. “Physical”, the team from Türkiye, and “the Spallateam”, from Belgium, came to CERN, while DESY hosted the “Dawson Technicolor” team from Canada and the “Pumas in Kollision” team from Mexico. The “team XTReme” from the USA was invited to the University of Bonn to use its electron accelerator ELSA (the electron stretcher facility).

The collaboration between CERN and DESY on Beamline for Schools started in 2019 and, for the first time this year, the University of Bonn also welcomed a team. The participation rate has been rising consistently since the competition was launched in 2014. This year, more than 3500 high-school students participated, and a record number of 508 teams from 72 countries submitted an experiment proposal.
