ACTINIS – Shielded Ion Microprobe
High Performance Shielded SIMS Instrument for the Analysis of Radioactive Samples
Dynamic Secondary Ion Mass Spectrometers (SIMS) are known to be extremely useful for a wide range of nuclear science applications, but the investigation of highly radioactive materials, such as irradiated nuclear fuel, requires specifically designed equipment. Derived from the field-proven CAMECA IMS 7f system, ACTINIS is designed to perform high precision elemental and isotopic analyses of radioactive samples in a safe environment: it is integrated in a set of biological protections in order to protect operators from contamination and irradiation effects during sample transfer and analysis, and includes specific adaptations to minimize manual operations such as a full-security sample introduction system.
Product Details
Benchmark SIMS performance
Retaining the best features of the IMS 7f / 7f-GEO models, ACTINIS delivers high sensitivity depth profiling and isotope ratio measurements as well as element and isotope mapping at sub-micron lateral resolution.
Combination of Duoplasmatron and Cesium primary ion sources ensuring optimum sensitivity to electropositive and electronegative species
Optical collection system for high impact energy secondary ions for best transmission, beam centering for excellent reproducibility and gating for high dynamic range depth profiling
Double-focusing mass spectrometer (electrostatic analyzer for energy focusing, laminated magnet with rapid peak switching)
High precision detection system with one Electron Multiplier (EM) and two Faraday Cups (FCs) with state-of-the-art electrometry (low noise and stable baseline)
Scanning ion imaging for instrument tuning and in-situ mapping of areas with high lateral resolution
State-of-the-art shielding
The mechanical drawings and detailed specifications for the biological shielding ensure radiation protection and seamless interfacing with the SIMS instrument. Thanks to a specialized glovebox (Alpha protection) and a lead-shielded cell (Gamma protection), ACTINIS can analyze samples with activity (dose rate) of up to 2 Gy/h, measured at a distance of 5 cm from the sample.
Ease of use
ACTINIS offers specific adaptations designed to minimize manual intervention, such as a highly secure sample introduction system. Specialized tools have been developed and ion-optical components modified to enable maintenance within the shielding.
Inspired from the Greek ἀκτίς (ray), ACTINIS™ also refers to actinides, chemical elements of particular importance in nuclear applications.
