Tungsten Filament Gun. Tungsten is normally used in thermionic. Automatic monitoring and control of filament. the advent and use of the field emission gun has revolutionised the use of the scanning electron microscope (sem). as previously introduced, the simplest source of electrons in an electron gun cathode could be a metallic wire or filament such as tungsten bent into a hairpin shape, where we apply a small voltage to pass a current through the wire’s resistance to heat the wire. features of our proprietary intelligent filament technology (ift): the electron beam comes from a filament, made of various types of materials. in electron microscopes, a field emission gun is used to produce an electron beam that is smaller in diameter, more coherent and. This filament is a loop of. The most common is the tungsten hairpin gun. in a typical sem, an electron beam is thermionically emitted from an electron gun fitted with a tungsten filament cathode.
