Registrations for 2020 now open!

Participants will be welcomed at CERN’s S’Cool LAB for an introduction to particle physics, and invited to study actual particle tracks observed in CERN's detectors with the help of our scientists.
Starting with a guided tour of the Laboratory, the day ends with a videoconference (in English) during which the pupils share their results with their counterparts in other institutes around the world taking part in the programme on the same day.

The Masterclasses are aimed at pupils studying science in the last two years of secondary school in France and Switzerland (i.e. 1ère or terminale scientifique in France or third and fourth years of the option scientifique in Geneva). The maximum capacity of the venue is 36 people, including the accompanying adults.
