Test requirements for users coming to PETRA III / FLASH

  • a negative PCR test for SARS-CoV-2 with the result being available before entering the DESY campus is still required. The test result must not be older than 48 hrs. Vaccination or recovery from Covid-19 will not release users from this obligation.
  • during your stay here at DESY we recommend to carry out antigen selftests every second day. Please bring your own test kits.
  • do not come to DESY if you have corona-typical symptoms.
  • proof of vaccination is not requested anymore.

Please print out and pre-fill the routing slip and present it in the User Office along with your PCR test result.

We strongly recommend to use medical/FFP2 masks

For your own and the staff's safety we strongly recommend that masks are worn in all indoor areas.
Please wear masks when coming to the User Office to show your test result and get the routing slip signed.

When working close with others we recommend to use FFP2 masks.
In addition, please keep distance to other persons, which also means that you should restrict the number of persons being together in the beamline hutches and laboratories whenever possible.

Allowed number of onsite participants

There is no restriction in the numbers of participants anymore.
