CERN has announced the 4th edition of its Beamline for Schools Competition, which will see two winning teams of students undertake an experiment of their design at a fully equipped CERN beamline next year. The 2017 competition, which is made possible thanks to the Alcoa Foundation, is open to teams of high-school students aged 16 or older. A maximum of nine students per winning team will be invited to CERN, and teams can be composed of pupils from a single school or a number of schools working together.

Previous winners have tested webcams and classroom-grown crystals in the beamline, and also studied how particles decay and investigated high-energy gamma rays. Interested schools can pre-register their team to receive the latest updates, and further information about how to apply can be found at cern.ch/bl4s. The deadline for submissions is 31 March 2017.
