    E-Beam Tungsten Filaments

    Tungsten is known for its excellent thermal stability and high melting point, making it an ideal material for electron beam filaments. Electron beam tungsten filaments can withstand the high temperatures generated during the vaporization process, ensuring reliable, continuous operation over long periods.

    Electron beam tungsten filaments are an essential component in vacuum deposition systems, they use the power of electron bombardment to evaporate target materials. This evaporation process creates a flow of atoms or molecules that enables the deposition of thin films with excellent uniformity, density, and purity.

    We manufacture tungsten filament for all popular electron beam systems and offer OEM custom tungsten filament (JEOL, Leybold, Telemark, Temescal, Thermionic, etc.).

    What is an electron gun?

    tungsten filaments1_副本

    An electron gun is a device used to generate and control a focused beam of electrons. It usually consists of a cathode, anode, and focusing element enclosed in a vacuum chamber. An electron gun uses an electric field to accelerate electrons fired from the cathode to the anode, creating a concentrated flow of electrons.

    Electron guns are used in a variety of applications in science, industry, and medicine. Common applications include electron microscopy, electron beam lithography, surface analysis, materials characterization, electron beam welding, and electron beam evaporation for thin film deposition.
