Product description
The merchandise is described in your letter as an EB5 Electron Gun and filaments. The EB5 electron Gun consists of an electron source and its power supply. The source is a metal tube, about 1 1/2” in diameter, which houses a tungsten filament. The source is mounted on a flange on the wall of an ultra high vacuum chamber, which has a substrate. When power is applied to the filament and the extractor lens, electrons are emitted from the source and impinge on to the surface of the substrate. The filaments are made of tungsten or thoriated tungsten (for oxygen resistance) and are either wire or mounted (welded) on posts. These filaments occasionally burnout and are in need of replacements.
