Tungsten Filament in Electron Accelerator

An electron accelerator includes a vacuum chamber having an electron beam exit window. An electron generator is positioned within the vacuum chamber for generating electrons. A housing surrounds the electron generator and has a first series of openings formed in the housing between the electron generator and the exit window for allowing electrons to accelerate from the electron generator out the exit window in an electron beam when a voltage potential is applied between the housing and the exit window. The housing also has a second series and third series of openings formed in the housing on opposite sides of the electron generator for causing electrons to be uniformly distributed across the electron beam by flattening electrical field lines between the electron generator and the exit window. Tungsten filament is installed in electron equipment, to work with accelerator, film, exit window to emit the electron.

Electron Beam Tungsten Filament and Exit Window Foil

An exit window for an electron beam emitter through which electrons pass in an electron beam includes an exit window foil having an interior and an exterior surface with a series of holes formed therethrough. A corrosion resistant layer having high thermal conductivity extends over the exterior surface and the holes of the exit window foil for resisting corrosion and increasing thermal conductivity. The layer extending over the holes of the exit window foil provide thinner window regions which allow easier passage of the electrons through the exit window. And the emitting electrode is generated by tungsten filament with customized shapes.

Electron Beam Tungsten Filament Applications

Electron beam tungsten filament applications are coating thin film in making Christmas ball, bottle cap, shoe heel, reflection cap, lamp industry etc, as a heater in vacuum metalizing machine. Tungsten filament is with properties of high melting point, high resistance, good intensity and low evaporation pressure, suitable for making heating element. Placing film material (aluminum, chrome, indium etc.) in vacuum metalizing machine, with high vacuum, the heating element (tungsten heater) will evaporate the film turn into shiny and beautiful film.

Tungsten Cathode for Electron Beam Emitter

Design and development of an indirectly heated solid cathode for a linear electron beam emitter assembly can be found as following image. The solid cathode is made of tungsten with cathode shape, called tungsten cathode. Thermionic electron beams emitted from a directly heated strip shaped filament have been used to heat the cathode indirectly. The temperature of the cathode, measured by a two color pyrometer, was raised to 250002K. The innovative design of the cathode and its holding mechanism accommodates thermal expansion at high temperature, and prevents thermal deformation of the cathode. The cathode is suitable for use in strip electron beam gun and for laboratory experiments on melting and evaporation of refractory materials.

Electron Beam Emitter

An electron beam emitter including a vacuum chamber having a width. An electron generator can be positioned within the vacuum chamber for generating electrons. An elongate nozzle can extend from the vacuum chamber along a longitudinal axis and have an exit window at a distal end of the nozzle. The nozzle can have a width that is less than the width of the vacuum chamber. The electron generator can be shaped and dimensioned, and positioned with the vacuum chamber to form and direct a narrow electron beam that enters and travels through the nozzle, and exits out the exit window. Used for irradiation of bottle interior. Tungsten filament is a main part for emitting electron.
