The Mackay Microbeam Lab
The Mackay Microbeam Laboratory instrumentation provides powerful tools to investigate micron to sub-micron scale characteristics of minerals, metals, and other substrates. Our JEOL 7100 FE-SEM is fitted with secondary electron (SE), backscatter electron (BSE), and cathodoluminescence (CL) imaging detectors, along with energy-dispersive X-ray spectroscopy (EDS) and electron backscatter diffraction (EBSD) detectors for chemical and crystal orientation analyses. The ability to perform large-area mapping allows for collection of high-spatial resolution chemical and crystal orientation data for research in Earth Sciences, Chemistry, and Materials Engineering. The W-filament SEM is an essential tool that provides excellent SE and BSE images of larger-scale characteristics (10–100s microns) and EDS chemical compositions for identification of minerals and materials.

Instrumentation
- The lab hosts two scanning electron microscopes (SEM), one with resolution to 10nm and a high resolution system with sub-nm resolution
