\nThe LK Technologies Model EG3000 Electron Gun with matching control electronics is suitable for a variety of surface analysis applications such as Auger<\/a> 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 \u00b5A. With the standard refractory metal cathode, the gun provides a minimum spot size of approximately 1mm at a working distance of 75mm.

\nThe control electronics features an “autofocus” mode which maintains minimum spot size focus with beam energy variation as well as a “defocus” mode which allows operator adjustment to uniformly defocus electron beams up to 10mm in diameter (or greater, depending on working distance). The electron gun is fully UHV compatible, employs integral magnetic shielding and can be baked to 200\u00b0C. All electron guns are tested under UHV conditions prior to shipment. For special applications involving smaller spot sizes, cathode variations or other custom requirements, please consult LK Technologies.
