On 14 and 15 September, more than 150 activities will be offered to the 80 000 visitors expected on our sites. Volunteers will be the key to the success of this exceptional event. More than 2400 volunteers have already signed-up but we still need another 500 to fill the many roles that remain open.

Whether you are a member of CERN personnel, contractor’s personnel or Honorary Staff, everyone will have a role to play! The role assignments have already started. Instructions and other practical information can be found on cern.ch/od2019/volunteers.
