The FEI Quanta 250FEG’s mission is to image a range of radiological materials for research in nuclear forensics, nuclear energy, environmental management, and national security. Materials include, but are not limited to: irradiated fuels, reactor components, and “sludge” from tanks on the Hanford site.
The instrument’s unique environmental chamber also allows for analysis of non-conducting samples and several after-market detectors provide a broader range of imaging possibilities. The scanning/transmission electron microscope detector (STEM) detector, for example, allows users to see through a material rather than simply imaging the surface of it.
