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.
LK技術模型eg3000電子槍匹配電子控制適用于各種表面分析等應用俄歇電子能譜、電子散射和衍射實驗，和電荷中和。電子束的能量可連續變化的0.1-3 keV。電子束電流可從10鈉大于100μA.與標準的難熔金屬陰極，槍在工作距離75mm提供最小約1mm光斑尺寸。
The 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°C. 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.
電子控制功能的“自動對焦”模式，保持最小光斑尺寸的焦點光束能量的變化以及“散焦”模式，允許操作員調整均勻散焦電子束直徑達10mm（或更多，取決于工作距離）。電子槍是完全的超高壓兼容，采用整體磁屏蔽，可以在高壓條件下測試了所有的電子槍在高壓條件下裝運前200。對于涉及較小的光斑尺寸的特殊應用，陰極變化或其他定制要求，請咨詢路技術。
