A beam of electrons is produced at the top of the microscope by an electron gun. The electron beam follows a vertical path through the microscope, which is held within a vacuum. The beam travels ...

enabling us to see objects that are much smaller than anything a light microscope could reveal. The SEM is composed of several key components that each play a critical role: Electron Source or 'Gun': ...

when subject to intense electron bombardment in the electron microscope. While the results are not readily interpretable, they do suggest that the effects may not be entirely due to the heating ...

"With this microscope, we hope the scientific community ... To accomplish this, the physicists behind the new study tweaked an electron gun until it produced a pulse of just one attosecond.

What is Electron Backscatter Diffraction (EBSD)? Electron backscatter diffraction (EBSD), also known as backscatter Kikuchi diffraction (BKD), is a powerful characterization technique used to analyze ...
