A heated tungsten filament within the electron gun produces electrons that get deal with the specimen with the condenser lenses.
A differential pumping aperture is utilized to separate the gun chamber, pumped by the ion pump, from the remainder of the column in order to shield the electron gun from degrading.
The thermionic emitter is coupled to an electrode in The form of the cup with a small hole centered beneath the suggestion. Generally known as a Wehnelt cylinder, this machine helps to localize the emitted electrons and create a concentrated beam that can be even further manipulated through the illumination method.
