The Kimball Physics EGF-3104 Electron Gun, with its matching EGPS-3104 Power Supply, is intended for use in a variety of ultra-high vacuum (UHV) charging studies, space physics, vacuum physics, surface physics, and nuclear simulation applications. It is a complete subsystem ready to attach and turn on. Maximum flexibility is achieved in a minimum of space; the entire unit mounts through a single standard 2.75” inch CF port.
Electrons are generated at negative high potential, and the user’s target is typically set at ground potential. Both beam energy and beam current are adjustable over wide ranges. The gun uses a space-charge-limited refractory-metal cathode to generate a uniform flood beam and the design allows generation of the beam down to low energies, and very low currents. A high current option provides beam currents up to 1 mA. Beam divergence is partially controllable electronically over the full range of the electron energy.
