The Nondestructive Analysis (NOVA) Center located at Western Kentucky University is the only facility of its kind at a North American University, home to one of the world's largest Large Chamber Scanning Electron Microscopes (LC-SEM). A prototype of the LC-SEM was shown in the Hannover Industrial fair of 1995, attracting the attention of many researchers and scientists from the Engineering and Materials Science community. Since the beginning, the LC-SEM has been a product of interest for many types of test in a wide range of industries, from Archeology to Aerospace.

The Large Chamber Scanning Electron Microscope has great potential for observations of deformation behavior of materials, as well as for relatively small production processes in the field of micro-system techniques.

The Large Chamber SEM also makes it possible to perform “interrupted monitoring” experiments for larger engineering parts. The parts can be in service for a specific period of time followed by an investigation of the part in the LC-SEM and returned to service immediately after the investigation is complete.

This way of monitoring a system will open a very broad field for engineering applications that will allow a more detailed understanding for preventative maintenance.

Precision Analysis

The Large Chamber Scanning Electron Microscope (LC-SEM) will accommodate a sample up to 40 inches in diameter, 40 inches tall and up to 650 pounds (large enough for an automobile engine block) eliminating the need to cut samples into small pieces for examination.

Equipped with a positioning system that allows views from different angles the LC-SEM gives an extended view of an object being tested. By moving the electron gun and detectors around the object the LC-SEM is capable of generating images with a resolution of better than 10nm and a magnification up to 300,000X.

The magnification capability offers high resolution imaging for surface analysis, chemical analysis, materials identification, quality control, metal microstructure, subsurface examination and more.

High-Resolution Imaging:
Secondary Electron Imaging (SE) for topographic imaging
Back-Scattered Electrons (BSE) for elemental contrast imaging

Surface Characterization:
Energy Dispersive Spectroscopy (EDS) for chemical analysis

Expanded Material Range:
LC-SEM can operate in Variable Pressure (VP) mode that allows us to make measurements on nonconductive surfaces
