User Operations under COVID-19 conditions

Due to enhanced restrictions set out in the UK due to the COVID-19 pandemic Diamond will at this time only support experiments that can be carried out remotely or by mail-in. Currently we continue to run the beamlines according to a 4 day weekly schedule, Tuesday 09:00 to Saturday 09:00 until the end of March when we will review the schedule. We are unlikely to be in a position to support all experiments at this stage, even if they are individually feasible. For further details please see here.

For the next call covering July-December 2021 we assume the schedule will be determined by running the sessions over a normal 6-day week with some users (up to two) being able to visit Diamond to conduct their experiments. For further details please see here.

Testing for COVID-19 is possible at Diamond, see here for further information.

Diamond has created safe and manageable working protocols. Given the UK Government’s increase of COVID-19 restrictions however, Diamond Light Source will not at present be accepting users to site.

We have now opened most of Diamond’s instruments and we will continue to re-schedule feasible experiments into 2021, both re-scheduled and new proposals from the AP28 call.

It is still possible to run remotely with samples connected with work associated with combating COVID-19 either through an already approved BAG or through the rapid access submission.

Diamond is accepting rapid proposals for COVID-19 related research – see below for details.


Beamline working conditions

Diamond is currently operating to keep staff and users safe.

The working levels we have defined are different from the UK government levels - they are defined in this way:

Currently at Level 3 (experiments run by staff on behalf of users. Limited staff presence to run experiments. No users on site. Strict social distancing and working protocols.)

Level 2: We will attempt to schedule cancelled AP27 experiments that are feasible under Level 2 conditions. This means: Limited user presence on site, maximum 2 users at the beamline at any time. Limited staff presence. Strict social distancing and working protocols. Possibly beam available into the weekend. Staff will not be expected to be on site in the evenings or at the weekend.

Level 1: Experiments which require operation at Level 1 (normal user operation) are unlikely to be scheduled, and Principal Investigators are encouraged to re-apply with a simplified experiment when the next call opens.

When a new call for proposals is made, experiments will be assessed for their feasibility at the expected operating Level. 

We are panning to run the schedule of sessions over a normal 6-day week in 2021 with some users being able to visit Diamond to conduct their experiments. 

Please respect these points when writing your proposal:

  • Consider whether your experiment is feasible if no users can come to Diamond (Level 3).
  • We may be at Level 2, with only two users per experiment permitted on site at any one time, but shift working will be considered, with a total of 4 users working in teams of 2 people.
  • With limited user numbers per experiment, 24 hour operation may not be possible, due to the risk of user and staff fatigue.
  • Social distancing and COVID-19 working protocols increase the length of time required to perform tasks.
  • Ensure that you will have samples ready for scheduling at short notice. It will not be possible to accommodate user preferences for "good" and "bad" dates.
  • Beamline staff cannot take responsibility for setting up or operating sample environments owned by users.
  • Complicated, ambitious experimental equipment setups are not encouraged until we are confident that Level 1, normal user operation is possible.
  • As always, please discuss the feasibility of your proposal with beamline staff before submission.
  • Submit your proposals to UAS

The protocols Diamond works to can be found here.


Diamond continues to welcome all users to submit proposals and participate in experiments here. Users are welcome to come to Diamond for their research from anywhere in the world.

EU users coming to Diamond are advised to consult the formal govenment website for the latest updated information on what is required when arriving at the border. Please click here for more information.

Diamond also supports research submitted as part of EU grants. For more information on support for  European access to research in the life sciences, please see here.

Rapid Access Call for Proposals: SARS-CoV-2

Diamond would like to ensure that it is doing everything possible to support researchers in their efforts to discover more about the COVID-19 virus and bring us closer to an effective vaccine or treatment.

With this in mind, we are offering priority rapid access for groups who require instrument time for projects directly related to SARS-CoV-2 viral proteins. Based on the number and nature of requests for priority rapid access, Diamond will make every effort to satisfy research priorities.

Submit a proposal for COVID-19 related research using the rapid access form here.

Or contact the team here:

UK national information relating to COVID-19

Diamond is aligning its approach to this outbreak with PHE Advice (Public Health England’s advisory website) and UK Gov. Travel Advice - These pages are updated regularly and you are advised to check the latest UK government statements through these sites.

If you believe you are at increased risk for any other reason, please see: to discuss personal risk and then adhere to their advice.

Diamond's Values

Diamond seeks to foster a culture of working that is reflected in five values (Respect, Excellence, Collaboration, Integrity and Innovation). These values help everyone who comes here to work or use Diamond's facilities to have a common framework of understanding how we relate to each other and what we aspire to.


This benefits everyone: 

• Everyone is valued, trusted and respected regardless of their gender, location, age, ethnicity, beliefs, role, grade, religion or other personal attributes - treated with respect
• Diamond will be a great place to work
• Clarity on how to behave well and what you can expect from others
• Identify and plan development to meet the challenges of your current role and future roles
