JEOL JXA-8530F field emission electron microprobe analyzer (EMPA). It is equipped with five dual-crystal wavelength dispersive spectrometers, two 30mm2 energy dispersive silicon drift detectors (JEOL and Thermo-Noran) and a JEOL xCLent cathodoluminescence system. The instrument is also equipped with a cold trap and an in-situ plasma cleaner for minimizing sample contamination during carbon analysis. The instrument can be operated at up to 30 kV and beam currents of up to 1 µA. It has a practical spatial resolution of 5 nm for imaging and 1 µm for quantitative analysis. The electron probe is equipped with state-of-the-art software (JEOL, Probe for EPMA and xCLent Image) for combining and manipulating elemental and CL maps.
Emma Bullock operates Carnegie's one-of-a-kind JEOL 8530 field emission electron microprobe. Bullock trains and mentors new and visiting users, and collaborates with staff and postdocs on research projects. Additionally she, along with FIB Lab Manager Suzy Vitale, provides leadership to maintain and manage the smooth operation of the Electron Microscopy Suite. Over the course of her career, Emma has over 15 years of SEM and EMPA experience. Her research background is in the field of meteorites and the early solar system. Prior to joining Carnegie, she was a geochemist at the Smithsonian Institution.
