Abstract
The present disclosure is related to a Schottky thermal field (TFE) source for emitting an electron beam. Electron optics can adjust a shape of the electron beam before the electron beam impacts a scintillator screen. Thereafter, the scintillator screen generates an emission image in the form of light. An emission image can be adjusted and captured by a camera sensor in a camera at a desired magnification to create a final image of the Schottky TFE source's tip. The final image can be displayed and analyzed to for defects.
