Our Inside Diamond open day events offer the chance for members of the public to visit the facility and see inside our particle accelerator and experimental laboratories. You will also meet some of the scientists that use Diamond and can ask them about the work they do – everything from viral proteins to engine parts and ancient texts.

Date: Saturday 15 March 2025

There are several starting times for the visits which you can select during the booking process: typically 09:30, 11:00, 12:45 and 14:15.

Ballot entry closes on Sunday 16 February 2025.

These events are very popular and we have a limit on the number of visitors we can accommodate so we operate a ballot system to offer a fair allocation of spaces. For this reason, only one entry is permitted per household.

A typical visit will take approximately 2 – 2.5 hours and will consist of:

• An introductory talk giving a general overview of Diamond and what it is used for.
• A guided tour – including a trip to see inside the synchrotron and our laboratories (please note that extensive walking will be involved).
• An opportunity to talk to Diamond employees and ask them about their work and the facility.

Advice / Restrictions:

• Due to the size of the facility, there will be extensive walking involved during the guided tour and as such, we advise all visitors to wear comfortable footwear.
• Due to the nature of the facility, we do not admit visitors under the age of 6 and we recommend that the visit is more suitable for adults and children aged 11+.
• There are a few restrictions due to health and mobility issues, although we ask that you inform us of any special requirements during registration so we can ensure suitable tour routes are available.
• Please be aware that it can feel quite warm in the Synchrotron building so be prepared to remove extra layers/coats during tours.
