Evaporating Gold in an e-Gun™ source
Application Note: Evaporating Gold (Au) in an e-Gun™ source For Gold, the best liners are Coated Graphite and Intermetallic (Ti doped BN). You should not sweep during coating. You can sweep during material conditioning, but once the material is fully melted, just place the beam in the center of the pocket. This will give the […]
e-Guns™
Introduction The Thermionics Laboratory e-GunTM, an electron beam evaporation source, is used to produce uniform high-purity films and optical coatings. The compact design and ease of maintenance make it useful in practically all vacuum systems and for many varied applications. It has been used to evaporate refractory and dielectric materials, as well as the more […]

Ground System for e-Guns™
The ground system is a very important aspect of the installation of the electron beam equipment. The vacuum tank and the power supply must be connected to a good earth ground. Under normal conditions, a good earth ground will consist of a ¾ inch diameter copper-clad rod driven into the floor at the vacuum tank […]
Evaporating Aluminum in an e-Gun™ source
Application Note: Evaporating Aluminum in an e-Gun™ source Aluminum (Al) is highly reactive when molten. Al will react with all liner materials. Al also getters Oxygen to form oxide layers if any oxygen is present during deposition. Aluminum Oxide (Al2O3) has a much higher melting point and vapor pressure when compared to Al (2,045C M.P., […]
