Extract

When managing multi-disciplinary materials characterization facilities to help solve scientific materials problems, one needs to confidently operate the instrumentation knowing that the calibrations and operational procedures are as accurate as possible and optimized by periodic evaluation. An overview of the calibrations and some operational pitfalls will be reviewed for the Analytical Electron Microscope. I intend to show examples of various results produced over the years characterizing materials, including some recent data. A short chronological history of my career pertaining to image documentation will show examples from the old days to the present. I pride myself on having a top-notch laboratory so when scientists need relatively fast answers, one knows which direction to proceed and the equipment is capable of achieving the results. When scientific users come to an AEM laboratory, each individual brings a potpourri of materials problems to try and solve.
