Get Involved

• Join FCC
  • Is your institute registered in the Grey Book? Check. If not, register here.
    • The CERN Grey Book database stores data on all the approved experiments and projects, their collaborating institutes and their participants. FCC is an approved study for future colliders at CERN. Registering in the Grey Book incurs no commitments, and no deliverables are expected until the FCC is approved. However, it is important to recognize the interested parties which will help in subsequent planning and execution of the project.
  • Can you sign the MOU?
    • A signed FCC MOU between an institute and CERN allows the institute to have a representation in the FCC Collaboration Board with full voting rights. More information on MOUs can be found here.
