Varian 981-2125 Electron Gun
- Produces a finely controlled primary beam over the energy range from 200 eV to 3 keV at beam currents from 1.0 uA to 30 uA in the Auger mode.
- In the LEED mode, beam energy ranges from 3 eV to 1.5 keV. (Current level is typically 1 uA at 100 eV.)
- Beam diameter is less than 1 mm above 50 eV; between 5 eV and 50 eV, beam diameter is less than 2 mm.
- Filament assembly which is mounted at an angle 13 deg. off the main gun axis so that there is no line of sight between filament and sample. This minimizes the possibility of sample contamination from the filament and also reduces the light reflection from the sample onto the screen..
