Behind the Scenes: New tabletop SEM

See what Center researchers are currently working on in this special behind-the-scenes feature!

Director Dr. Rhonda Stroud stands next to the Center’s new variable pressure and cerium hexaboride (CeB6) source scanning electron microscope (SEM).

This state-of-the-art SEM comes equipped with backscatter and secondary electron detectors for imaging at resolutions down to 10 nanometers, and an energy dispersive X-ray spectroscopy system for compositional analysis.

The 100 mm2 stage accommodates large, unpolished meteorites samples, but will be equally helpful for analysis of microparticles such as returned asteroid Ryugu and Bennu samples, lunar soils and cosmic dust.
