Scientific Description
CNRS and CEA, in agreement with the French Ministry of Higher Education and Research, have set up a national network of accelerators dedicated to material irradiation. This network consists of 5 platforms with unique equipments and specific expertises: Provide academic and industrial researchers from the national and international communities access to irradiation facilities and online characterisation, Provide scientific expertise on ageing of materials, material science, …Foster instrumental developments, Organize training (workshops, academic training,...) and outreach.

JANNuS – Orsay platform

The JANNuS – Orsay platform is comprising a 200kV TEM connected at the 2 accelerators, to observe in real time the structural evolution of materials in experimental conditions between 77K and 1300K. Every experiment requires the presence of an experienced microscopist, presence which must be planned by the proposing researcher.,43-

JANNUS Saclay installation

JANNUS Saclay installation currently consists of three electrostatic ion accelerators. The first machine is a 3 MV Pelletron accelerator equipped with an ECR source and can provide multi-charged ions. The second machine is a 2.5 MV single floor Van de Graaff equipped with a radiofrequency source. The third machine, a 2 MV tandem with source SNICS-II, has been put into service in November 2009.

CEMHTI ion accelerators

The CEMHTI has two ion accelerators, a cyclotron and a van de Graaff used for research in different fields and open to the scientific community. The characteristics of available beams are deferred in the following table. It should be noted that neutron irradiation are also possible. In recent years the CEMHTI, through its technical potential, has developed various devices for irradiation with characterization techniques online (Raman ...),29-

ARAMIS & IRMA accelerator

The group Semiramis of CSNSM has in charge two accelerators. They allow irradiation and ionic implantation in an energy range between 10 keV and 15 MeV for out-of-equilibrium synthesis of new materials. They offer the possibility to characterize materials by ion beams (Channelling RBS, ERDA, PIXE) or by Transmission Electron Microscopy (TEM). A dedicated ion beam line is available to install voluminous experimental equipments. The two accelerators are linked by an ion beam line to perform, without changing experimental conditions, implantations and ion beam characterization.,43-

EM7 High Voltage Electron Microscope (HVEM)

The EM7 High Voltage Electron Microscope (HVEM) located at CEA Saclay has been operated since 1981. Upgrading/rejuvenation of the microscope was carried out very recently in order to insure reliable operation in future years. Electron irradiation experiments at high damage rate (typically up to about 5 10-3 dpa/s in iron/steels) can be performed using the EM7 microscope, under very good vacuum (< 5 10-8 Torr). Irradiation effects can be studied either in-situ in the microscope and/or specimens can be characterized ex-situ following the irradiation. The samples which can be irradiated in the microscope are mostly conventional TEM thin foils, 3mm in diameter. Recently a new single tilt heating specimen holder dedicated to Atom Probe tips was designed and fabricated and will be tested shortly. Depending on the needs, it would be possible to design other dedicated holders.

CIMAP-GANIL ion beams

Interdisciplinary researches with the GANIL ion beams are managed by the CIMAP. For this research, CIMAP has developed beam lines and specific equipment to all levels of ion acceleration. Only ions from cyclotrons injectors (IRRSUD equipment) and the first CCS cyclotron (Medium Energie Line SME) will be open to the reception in the network EMIR.
