The LK Technologies Model EG3000 Electron Gun with matching control electronics is suitable for a variety of surface analysis applications such as Auger electron spectroscopy, electron scattering and diffraction experiments, and charge neutralization. The electron beam energy can be continuously varied from 0.1-3 keV. The beam current is adjustable from 10 nA to greater than 100 µA. With the standard refractory metal cathode, the gun provides a minimum spot size of approximately 1mm at a working distance of 75mm. Performance Features - operation from 100-3000eV - compatible with AES, charge neutralization and other surface analysis applications - auto focus mode for small spot applications - defocus mode for broad beam applications - fully UHV compatible and bakeable - integral magnetic shielding
