  • To strengthen the security of our services, a double authentication is needed when connecting to this portal. Guidelines available here.
  • ZAC (Zone accès controlé): Reception at the ZAC entrance is open during the week until 7pm, Monday to Saturday, but closed on Sundays.

  • Administrative screening ('criblage') for all persons requiring access to the ZAC (Zone accès controlé) is required. No access will be granted to the ZAC without screening.
    It takes up to 21 days to process security screening and the application for screening will only be sent once you register for the experiment.
    Once the screening application has been validated and access granted, an information message will be added to your personal data on your User Club account. (Personal Data tab)
