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 1700 volunteers have already signed-up but we still need another 1000 to fill the many roles that remain open.

Whether you are a member of CERN personnel or contractor’s personnel, everyone will have a role to play! The role assignments have now started so please sign-up before 31 July. Instructions and other practical information can be found on cern.ch/od2019/volunteers.
