Different filaments have differences in electron source size, current capacity, current stability, and electron source lifespan. The cheapest and most commonly used is tungsten filament, which emits electrons through thermal ionization. The diameter of the filament decreases with the evaporation of the tungsten wire during use, and its service life is40-80 hours.
