The next Inside Diamond event will take place in person on Saturday 15th March 2025 and the ballot for this event is now OPEN. The ballot will close on Sunday 16th February 2025. You will be contacted 48 hours after the closing date.

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.

Inside Diamond - In Person Public Open Days

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.

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

There are several starting times for the visits which you can select during the booking process (typically 9:30, 11:00, 12:45 and 14:15).

Advice/Restrictions:

Due to the size of the facility, during the guided tour there will be extensive walking involved, 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+.
We have very few restrictions due to health and mobility issues, although we ask you to tell us of any special requirements during registration so we can ensure suitable tour routes are available.
Please also be aware that it can feel quite warm in the Synchrotron building, so be prepared to remove extra layers/coats during tours.

We also run dedicated school open days and university visits.
