Event Navigation

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 21st March 2026
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 at midnight on Sunday 15th February 2026. You will be contacted within 1 week of the closing date.
These events are very popular and we can only accommodate a limited number of ‘in person’ visitors. To ensure a variety of visitors can join us, we limit tickets to 6 people per ballot entry.
A typical visit will take approximately 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 engage with demonstrations and activities run by Diamond staff, users and partner institutions.
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+. Visitors under the age of 16 must be accompanied by an adult.
- 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.
Ballot entry closes at midnight on Sunday 15th February 2026. You will be contacted within 1 week of the closing date.
