Joint Accelerators for Nanosciences, Nuclear and Simulation

JANNuS, a multi-ion beam irradiation platform

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


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.
