  • ILL is a member of CRISP, the Cluster of Research Infrastructures for Synergies in Physics

Colloquia at ILL

The ILL runs a colloquium series at which prestigious speakers are asked to give exciting and accessible talks of general interest to scientists having a wide range of backgrounds. In the past, ILL colloquia have included the Astronomer Royal, the editor of Nature, Hélène Langevin-Joliot (Marie Curie's granddaughter), and Sir Tim Hunt (Nobel Prize 2001).

More information on past and future colloquia here.

The ILL modernisation programme (2001-2014)

In order to keep the ILL at the forefront of neutron science and to provide the best possible experimental facilities and support to its European users over the next two decades, the ILL is modernising its infrastructure and instrument suite.

85 M€ are invested to boost instrument efficiency.

The scientific results of the first phase are already impressive: the average detection rate of neutrons for all instruments was improved by a factor of 20!
