Kimball Physics is a key supplier of electron guns designed for use in a wide variety of ultra high vacuum (UHV) surface physics, space physics, and processing applications. Guns can be focusable for small spot size, for use in applications such as x-ray production, welding and RHEED; or for food beams, for use in charge neutralization, electron beam scrubbing, space simulation and radiation damage studies.
Range Of Operation
- Energy Ranges: 1 eV to 100 keV
- Beam Current Ranges: 1 nA to 20 mA
- Spot Size Ranges: 15 μm (focused column) to 500+ mm (flood beams)
Convenience
