Established in 2015, the Mackay School of Earth Science and Engineering Microbeam Laboratory houses two state of the art JEOL scanning electron microscopes (SEM), a field emission SEM and an easy to use portable tungsten-filament SEM. The field emission SEM has an Oxford energy dispersive spectroscopy (EDS) and electron backscatter diffraction (EBSD) systems and a Deben cathodoluminescence (CL) detector. The tungsten-filament SEM has low-vacuum capabilities, which allows for examination of biologic and other moist materials. The lab is transforming research in the Earth Sciences at Mackay and within the College of Science and is being used increasingly by other departments and colleges at UNR. The machine is also utilized by entities outside UNR, fostering cooperation and collaboration among UNR, the city of Reno, greater Nevada, and researchers throughout the world. Our mission is to make the Mackay School of Earth Science and Engineering Microbeam Laboratory the microscopy lab of choice for the western U.S.
