A metal element is heated by a low voltage and electrons ‘boil’ off the surface. Simulation of a fine beam tube showing an electron gun in use. Electron guns work by repulsion not attraction If you give the element a very high negative volt...

The Electron Gun (under construction) ... Much in the way that an incandescent lightbulb works, the high voltage that is fed through the filament causes electrons to be kicked off the filament. The amount of energy required is known as the work function.

This is the type of electron gun used in most electron microscopes. It is robust, relatively cheap and does not require an ultra high vacuum. In the thermionic electron gun, electrons are emitted from a heated filament and then accelerated towards an anode;

transmission electron microscopy alignment for beginners - learn to use TEM fast ... The filament or source - the first thing we ever made an image of in the microscope - is part of what is called ‘the gun assembly.’ The gun shoots electron down into the microscope. It’s worth having some idea how it works.
