The miniature electron gun G10 series’ small size gives it flexible mounting configuration abilities along with easy fitting to any system. The electron gun is equipped with a thoriated tungsten filament that has an operating energy range of 5 – 3000 eV.
- Miniature lens design
- Variable beam diameter
- Variable beam energy
- Low outgassing rate
- Flexible mounting configuration
The miniature size of the Electron Gun G10 series allows it to easily fit to any UHV system. It is a convenient tool for many applications especially LEED and AES experiments.
For seamless integration, 3D step files are available for all models.
