Electron Microprobe

The field emission electron microprobe capability will enable non-destructive imaging and compositional elemental analysis of solid-phase materials at high spatial resolution with parts per million (ppm) sensitivity to aid in analysis of inorganic and radionuclide fate and transport in geochemical systems. Its cathodoluminescence capabilities will afford identification of episodic growth in minerals. Initial experiments conducted on natural rocks from the Hanford Site will provide complementary data to ongoing activities in EMSL's microfluidics and Subsurface Flow and Transport capabilities. This instrument, to be housed in EMSL's Radiochemistry Annex, will enable chemical analysis and imaging of radionuclides with high spatial resolution in radioactive samples.
