A new shielded IMS ion microprobe to equip CEA Cadarache

Wednesday, July 17, 2019

CAMECA is delighted to announce that the CEA (French Alternative Energies and Atomic Energy Commission) recently placed an order for a shielded magnetic sector SIMS instrument to equip its Cadarache research center. The instrument will replace the 20-year-old shielded IMS 6f already in place in the micro-analysis laboratory (DEC/SA3E/LCPC) located in the LECA-STAR facility, and will provide crucial information for the studies on irradiated nuclear fuels.

Shielded SIMS instruments offer all necessary protections against radiation and alpha contamination during sample transfer and analysis while ensuring benchmark SIMS analytical performance. The new Shielded IMS 7f model benefits from hardware and software developments recently implemented on the latest generation CAMECA IMS 7f, including the robust electronics system, a new user interface, user-friendly acquisition and processing software, etc... Compared to previous Shielded IMS 6f, it will bring benefits in terms of performance, productivity, ease-of-use, and of course, uptime and sustainability.

Studies performed with SIMS on irradiated nuclear fuel focus on three main axis:

  • the nuclear reactions occurring during in core irradiation which are characterized with isotopic ratio measurements,
  • the physical and chemical behavior of fission products which is evidenced by isotopic cartography,
  • the characterization of fission gases which is carried out through depth profiling measurement.
The French Alternative Energies and Atomic Energy Commission  (CEA) is a key player in research, development and innovation in four main areas: low carbon energies, defence & security, technological research for industry, fundamental research in the physical sciences and life sciences.
