  • Updated COVID-19 measures please refer to :
  • ZAC (Zone accès controlĂ©) THe ZAC is in service. Access to the ZAC will be possible with a badge programmed for the duration of your stay, in a way very similar to the previous badges. However, your badge will be programmed in two steps Upon arrival, you must stop at the site entrance as usual to get a badge which gives access to all buildings on the campus outside the ZAC. You will be required to show proof of identity (passport, ID card) as usual. Then you must go the ZAC main entrance (ground floor reception in the new ILL50 building) where your badge will be programmed to enter the ZAC. Your dosimeter will also be distributed at this stage. 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 building ILL5 (Level C and D).
    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. More information here:
