Scanning electron microscope
The JEOL 5600LV scanning electron microprobe (SEM, Green 034) is jointly operated with the Stanford-USGS Microanalytical Center (SUMAC), where it is often used to obtain electron and monochrome cathodoluminescence (CL) images of minerals for analysis on the SHRIMP-RG ion microprobe. The SEM provides routine electron images at magnifications up to about 2000x. The microscope has an EDX (energy dispersive X-ray analysis) system for qualitative compositional measurements and imaging, which requires cooling with liquid nitrogen. Samples must be vacuum-compatible and are typically mounted on standard SEM “stub” holders. Samples must be electrically conductive or coated with a thin layer of gold, which can be done in the facility.
