The Kimball Physics EGF-6115 Electron Gun with its matching EGPS-6115 Power Supply is a complete subsystem ready to attach to the user’s vacuum system and turn on. It can deliver electrons over a broad range of energies, currents, and power. The EGH-6115 is a high- power, focusable flood gun for use in spacecraft materials testing and other surface physics and general vacuum physics applications.

The gun can generate a high energy, adjustable divergence, flood electron beam. Both beam energy and beam current are independently adjustable over wide ranges; energies from 1 keV to 50 keV and currents from pico-amps (pA) to five milliamps (mA) can be achieved. The electron beam can be pulsed by an input signal to the control grid.

The adjustable optics of the gun can adapt to different divergences and different working distances. Rastering / beam washing is used to provide a large uniform spot. Electrostatic focusing provides control  of the spot size, which is typically in the tens of centimeters. The flood beam is also partially dependent on the grid, anode and working distance.

The firing unit cartridge (including the cathode, cathode-mount, and Wehnelt aperture) is user-replaceable without removing the entire gun from the vacuum chamber; used firing units may be returned to the factory for rebuild.
