1. Latest COVID-19 restrictions at the ESRF (30 April 2021)

The additional lockdown restrictions imposed since 3rd April will be lifted from Monday 3rd May; external users are allowed back on the ESRF site within the limitations described below.

Remote experiments are possible and desirable, when appropriate, for all users, but onsite access is limited to users from countries within the "European area" (European area = all EU member states, Schengen countries, Andorra, Vatican City, Saint-Marino, and Monaco).

Until the current restrictions from the French Government concerning travel to France are lifted, it is unfortunately not possible for users whose laboratories are in countries outside of the European area to come to the ESRF site for an experiment due to the requirement for mandatory quarantine (ESRF member country states particularly affected are UK, Russia, Israel, South Africa and India).

Please note that intended beamtime for experiments impacted by these restrictions will not be lost if it can be taken before the end of the 2021 operation year (by end of February 2022). If the experiment permits, it should be carried out remotely, otherwise it will be postponed until later in 2021 if users are able to come on site by then. If there is a chance that the beam time cannot be used before the end of February 2022, users will have to reapply for beam time at the 10th September 2021 proposal submission deadline.

Users coming from within the European area may still come to the ESRF for experiments, but must be able to show a negative PCR test, taken within 72h of travel, to the French authorities on arrival in the country, and are advised to restrict their movements both onsite and offsite.

In general, for the coming runs 2 and 3 (April-May and June-July 2021),

  • Remote experiments should be carried out whenever possible;
  • When user presence on site is required, up to a maximum of 3 members of the external user team will be allowed to be present onsite, to improve the efficiency and success of the experiment, with the rest of the team joining and participating remotely. The number of onsite users must be kept to the strict minimum required to successfully carry out the experiment, i.e. if the experiment can be done successfully with one user onsite, only one user should come; if it needs two onsite, only two should come, etc, up to a maximum of 3 users.
  • In all cases, the maximum limit of users/staff allowed in a beamline hutch at any time must be respected at all times.

We will be very happy to welcome users back on site, but strict hygiene and social distancing measures remain in place and we kindly ask for your cooperation in respecting these rules before, during and after your visit.

Users should ensure that any formalities are completed in a timely fashion to allow them to arrive on the ESRF site in time for their experiment.

2. Latest COVID-19 restrictions in France (30 April 2021)

National, local and travel restrictions are constantly evolving so please ensure you are aware of the restrictions in place in France and in the Grenoble area at your time of travel, and ensure you are able to provide the correct paperwork and test results if required.

On the web page of the European and Foreign Affairs Ministry, the "European area" is stipulated as including all EU member states, Schengen countries, Andorra, Vatican City, Saint-Marino, and Monaco.

Restrictions for travelling to France from a non "European area" country

Travel to France from a non-European area country is forbidden, except for certain urgent and compelling reasons ("motif impérieux") of a family/personal, medical or professional nature. In such cases, people travelling to France from a non-European area country must :

  1. Complete, sign and provide the appropriate declarations as described here, and provide the associated justifying documents attesting to the important and urgent nature of the travel.
  2. Show a negative PCR test before travelling, AND
  3. Self-isolate for 7 days on arrival in France (10 days for Argentina, Brazil, Chile, India and South Africa), AND
  4. Then take a second PCR test after those 7 (10) days before being allowed to circulate freely.


Since 15 March 2021, Australia, South Korea, Israel, Japan, New Zealand, United Kingdom and Singapore no longer require a compelling reason for travel. However travelers arriving from these countries must comply with points 2 to 4 of the procedure described above.

Restrictions for travelling to France from a "European area" country

Travel to France from a European area country is not advised unless absolutely necessary. People travelling to France from a European area country must show a negative PCR test, taken within 72h of travel, to the French authorities on arrival in France. All types of travel are concerned (air, train, bus, car, sea).

A quarantine period is not obligatory for travellers from a European area country, except in the case of travel outside of the European area in the month before arrival in France.

Proof of essential travel is not necessary, but we still advise you to bring your experiment invitation with you.

In addition, please remember to ensure you complete any obligatory travel documents required by the French authorities and the airline companies.


A nightly curfew is currently in place in France from 7pm to 6am : users who will travel in these hours must ensure they carry with them a completed exemption certificate (French and English versions available) as well as written proof of their experiment invitation and their travel tickets.

During curfew hours while staying at the Guesthouse, users must not leave the site for any other reason than one of the reasons stated on the exemption certificate. If the curfew is not respected, a fine of 135€ will be imposed by the French authorities. Outside of the curfew hours users can leave the site and move around freely in the Grenoble area.

3. Travelling back to your home country

Users are responsible for checking restrictions related to their travel back to their home country.

Antigen tests

If needed, users can get an antigen test done free of charge on the EPN site by our Medical Service, during working hours (8am to 11am and 1:15pm to 4pm on week days). Please ask your local contact for the telephone number of the Medical Service so you can make an appointment with the works Doctor.

Option 2: PCR test service off site through a private laboratory

There are multiple laboratories in Grenoble where users can get a PCR test done ( The closest one to the ESRF is:

Oriade Noviale Berriat
Tram stop Saint Bruno on tram B, just before the train station.
Open from 9:30am to 11am and from 2pm tp 5pm on Monday to Friday
   and from 8:30am to 11am on Saturdays.

It is not necessary to make an appointment in this laboratory prior to the visit, but waiting times may be long so you are encouraged not to wait until the last minute.

Tests can be done without a French social security card and without a doctor's prescription. However, in this case, the test will cost around 65 €. ESRF reimbursed users may request an ESRF contribution for the cost of PCR tests up to a limit of 140 € per reimbursed user per experiment session by filling in a reimbursement claim and providing an invoice or receipt. The test must be directly related to onsite presence for a user experiment.

The results of the PCR test should be provided by the laboratory within 24 hours. Users will have to communicate their mobile phone number to the laboratory to be able to access their results using the link sent to them by text message.
