CERN is pleased to announce the 5th edition of the Beamline for Schools competition. Once again, in 2018, a fully equipped beamline will be made available at CERN for students from all around the world. The 2018 competition is made possible thanks to the Arconic Foundation supporting Beamline for Schools (BL4S) for the third consecutive year.

The competition is open to teams of high-school students, if they win, are invited (with two supervisors), all expenses paid, to CERN to run their experiment. Teams must have at least five students but there is no upper limit to a team's size (although just nine students per winning team will be invited to CERN). Teams may be composed of students from a single school, or a number of schools working together. Shortlisted teams will win a BL4S t-shirt for each team member and a cosmic-ray detector for the school. All participants will receive a certificate.

Think of a simple, creative experiment and submit your writen proposal and short video by 31 March 2018. The registraton for 2018 is already open! Dive into the fascinating world of particle physics and join the adventure.


Can high-school students conduct physics experiments just like real scientists? Two teams of students from Italy and Canada proved that they can.

After winning the 2017 Beamline for Schools (BL4S) competition, "TCO-ASA" from Fermo, Italy, and "Charging Cavaliers" from Cambridge, Canada, came to CERN for two weeks to conduct their own experiments at a fully-equipped CERN beamline. The teams were selected out of 180 applications.

The Italian team, consisting of eight students, designed and constructed a simple and low-cost Cherenkov light detector. Cherenkov light is a phenomenon observed when particles pass through a medium with a speed higher than the speed of light in that medium. The students assembled a light-tight plastic box filled with water. A sensitive camera and a silicon photomultiplier placed outside the box were used to detect the flashes of Cherenkov light inside.

Besides working on their physics projects, the students had a full day of safety training and visited various CERN facilities. In four shifts per day the students worked in the control room and the T9 beam line in the East Hall, while at the same time several volunteers helped them with data acquisition. For more than 10 days they lived the life of a scientist. "Everyone is so knowledgeable, friendly and open. We talked to scientists and they were all welcoming," said Marina Robin from the Canadian team.

Beamline for Schools is an education and outreach project funded by the CERN & Society Foundation, supported by individuals, foundations and companies. The project is funded in part by the Arconic Foundation and additional contributions are received from the Motorola Solutions Foundation and National Instruments.

The 2018 BL4S competition has already been announced and more than 60 teams have already been pre-registered. Proposals will be accepted until 31 March 2018. We are looking forward to another exciting run of Beamline for Schools in the year to come!
