Due to Covid-19 restrictions, at present Users are only allowed to access the CERN site if their presence is considered essential and has been approved via email by the ISOLDE Physics coordinator or the ISOLDE Physics group leader in agreement with the Users home institution. Any request should specify the reason and motivation for the visit as well as the duration.
Please note that Users will also need to follow the Covid-19 related instructions found on the Users Office website which includes an extra online course, a self-declaration form and CERN's strict quarantine requirements. If the user is coming from a region classed as high-risk by either France or Switzerland they must declare their planned arrival date to the CERN medical service, via email@example.com , who will then decide what quarantine measures are required.
CERN has arrangements with certain hotels where Users can stay if they need to quarantine, see here.
More information for Users about the CERN Covid-19 response as well as all related rules and regulations is available via https://usersoffice.web.cern.ch/ .
