The Institut Laue-Langevin (ILL) is a research reactor located in Grenoble, France. It was founded in 1967 (and renovated between 1993 and 1995) and is named after two prominent scientists: the German physicist Max von Laue and the French physicist Paul Langevin.
It is the world's most intense continuous neutron source, with a thermal power of 58.3 megawatts using a uranium-graphite core to generate the neutrons. The reactor operates continuously for 50 days, followed by a refueling outage. A longer outage is planned every year to allow for maintenance work. There are normally 4 cycles in a year, providing 200 days for science.
However, it is scheduled to close in 2024 and the scientific community is working to develop a new neutron source to replace the ILL. This new source is expected to be operational in the early 2030s.
In total, some 1,800 researchers from 45 countries use the neutron source for 800 experiments each year.
ILL has been used for a variety of research:
The ILL is an important facility for scientific research. It has contributed to the advancement of a variety of fields and has had a significant impact on people's lives. ILL is a testament to the power of nuclear science and its potential to benefit humanity.
