There are no special requirements for people to be able to acces the West Area controlled zones. What everyone needs is: - a valid CERN registration - a film badge For the latter, if people want a temporary badge for a limited time (<2months) than there is no need to carry a medical certificate issued from their home institution. For periods >2months a certificate is required. I believe everyone will request a temporary badge. Those, can be collected upon arrival (and registration) at Cern, at building 24-E011. Please, make sure that people coming to Cern are informed. I am taking care of the safety authorizations and inspections to run the test. Cheers, Armando
