Laue-Langevin Institute
The Institut Laue-Langevin (ILL) in Grenoble is an international research center that operates the world's most powerful neutron source with its super- flux reactor (HFR) . Every year around 1,500 guest researchers conduct more than 800 experiments, mainly in the field of neutron scattering . The ILL is only a few kilometers away from Grenoble train station on a former artillery training area on the gravel peninsula in front of the confluence of the Drac into the Isère . It borders almost directly on the French Center d'études nucléaires de Grenoble. A branch of the EMBL and the ESRF have now also established themselves on the grounds of the ILL .
The facility, built as a swimming pool reactor , achieves a neutron flux of over 10 15 cm −2 s −1 . With beam tubes and neutron guides , the neutrons are guided to over thirty experiment stations.
history
Just a few years after the Elysée Treaty was signed , the ILL was founded by Germany and France in January 1967. It was named after the two physicists Max von Laue (Germany) and Paul Langevin (France). In 1971 the reactor became critical for the first time ; soon after research began, Great Britain joined as an equal partner in 1974. The operation of the institute is based on international agreements with a term of ten years each, which are not automatically renewed; however, the ILL is not an international organization , but a limited liability company under French law.
At the end of 1990 cracks were found in a built-in part of the reactor. That is why operations had to be temporarily suspended; A repair by replacing the entire pressure vessel was only decided after long negotiations as part of the due contract extension. On this occasion, Great Britain implemented a 50% reduction in its contribution. In the following years Italy, Spain, Switzerland, Russia and a consortium from Austria and the Czech Republic joined as so-called partners (not contracting states). Russia is doing its part by providing fissile material.
The ILL's directors included Heinz Maier-Leibnitz (1967–72), Rudolf Mößbauer (1972–77), Tasso Springer (1977–82) and Wolfgang Gläser (1986–89).
