Overview - JANNuS

JANNuS, a multi-ion beam irradiation platform

The JANNuS multi-ion beam irradiation platform was established in 2005 around two facilities:

JANNuS-Orsay: An experimental hall located in Orsay within the MOSAIC ion beam facility of the Laboratoire de Physique des 2 Infinis Irène Joliot-Curie (IJCLab). IJCLab is a joint research unit of Centre National de la Recherche Scientifique (CNRS) and Université Paris-Saclay. CNRS is acting through one of its institutes called Institut National de Physique Nucléaire et de Physique des Particules (IN2P3).
JANNuS-Saclay: Located on the CEA Paris-Saclay, it is part of the low carbon energies division (DES) of the Commissariat à l’énergie atomique et aux énergies alternatives (CEA).

Capabilities

Served by a knowledgeable scientific staff, the capabilities combine a total of five electrostatic accelerators for single beam, dual beam, and triple beam ion experiments and a transmission electron microscope for in situ studies.

JANNuS is dedicated to researches in the effects of ions in materials. Its particle beams make it possible to irradiate small samples in a perfectly controlled manner, and thus to observe and quantify the evolution of their microstructure (segregation, precipitation, formation of dislocation loops, cavities, bubbles, etc.) and service properties. Such a scientific platform has no equivalent in Europe and plays an essential role for multi-scale modeling of radiation effects in materials.
