What is the ILL?

Founding papers of the ILL and its High Flux Reactor

In 1971, 20 founding papers were published by the teams of the Institut Laue-Langevin (ILL) and the Commissariat à l'Energie Atomique (CEA) involved in the design and building of the High Flux Reactor (RHF).

They were published in the now defunct and sold out CEA newsletter:

Bulletin d'Informations Scientifiques et Techniques
R. Juhel et G. Reynes, Ed. Dunod S.A., Paris and Centre d'Etudes Nucléaires de Saclay, Gif-sur-Yvette, France.
No 165, Dec. 1971, 100 pages  (accès restreint)
No 166, Janv. 1972, 70 pages


Created in January 1967 and built near the Grenoble C.E.N., the Max von Laue - Paul Langevin institute was responsible for the construction of a high flux reactor which became operational in December 1971. in this number an article outlining the aims and organisation of the Institute is followed by a complete description of this reactor, written by the various specialists who took part in the project.
