Electron Guns for AES, EELS, Imaging

Low cost focussed electron guns for AES, EELS and electron pulse/desorption experiments.

The ES 40C1 Electron Guns are scanning electron sources with small a spot profile. Due to the high transmission of its Einzel-Lens, the ES 40C delivers a high electron beam current over a wide energy range. The source insertion depth and shielding material (mu-metal or copper) can be chosen to match specific experimental requirements.

ES 40C1 Electron Guns: Application

The ES 40C1 electron Guns are designed for a stable and reliable operation in e.g. AES, scanning applications,imaging, EELS and electron pulse or desorption experiments.
