Group visits
The ILL welcomes group visits for scientific institutions, secondary schools, universities, and media representatives.
Visitor numbers are limited for safety reasons. Visits are available in French or English.
Three types of visits are offered:
For institutions or the media
We can accommodate groups of up to 30 people. Visits last approximately 2 hours and include:
- A general introduction to the ILL and neutron science
- A 1.5-hour tour of the experimental areas in smaller subgroups (maximum 10 people per group)
Visits for secondary schools
Access to the experimental areas is restricted to visitors over 18 years of age. For school groups, we offer an introductory presentation of the ILL in our exhibition space.
