The Kimball Physics EFG-7 Electron Gun, with its matching EGPS-1017 Power Supply, is intended for use in a variety of ultra-high vacuum (UHV) physics experiments, surface physics experiments, and processing applications. It is a complete subsystem ready to attach and turn on. Beam energy, beam current and spot size are independently adjustable over wide ranges.

The EFG-7 Electron Gun uses a refractory metal cathode to generate a uniform flood beam. The gun design allows for generation of the beam down to low energies, and very low currents. The standard model EFG-7 produces a beam current of 1 nA to 100 μA and energies of 10 eV to 1500 eV. A High Current option provides beam currents up to 1 mA.

Centering, deflection, rastering and pulsing are all available as options. Because the design has been optimized as a flood gun and uses a cylindrical 4-pole deflector, deflection aberrations can be severe when the beam is focused into a small spot.

UHV technology is used throughout. The gun can be run in vacuums from 10-11 torr up to 10-5 torr for the standard Ta disc cathode. The electron gun is bakeable to 350°C with cables removed. With Faraday cup, maximum is 65oC unless removed.
