The JANNuS is a multi-ion beam irradiation platform jointly managed by the "Commissariat à l’Energie Atomique" (CEA), the "Centre National de la Recherche Scientifique" (CNRS) and the "Université Paris-Sud 11" (UPS).
CNRS is acting through the "Institut National de Physique Nucléaire et de Physique des Particules" (IN2P3).
UPS, CNRS/IN2P3 are acting through the "Centre de Spectrométrie Nucléaire et de Spectrométrie de Masse" (CSNSM).
JANNuS is designed to supply a large range of ion irradiation and implantation conditions, allowing in-situ Transmission Electron Microscopy (TEM) and ion beam analysis with single, dual or triple beam combinations. Such a facilty has no equivalent in Europe and will play an essential role for multi-scale modelling of irradiation effects in materials.
