The Kimball Physics EGH-8105 Electron Gun, with its matching EGPS-8105 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-8105 is a high- power, focusable flood gun for use in spacecraft materials testing and other surface physics and general vacuum physics applications.

This is a high energy, focusable, flood electron beam system where both beam energy and beam current are independently adjustable over wide ranges. Energies from 1 keV to 100 keV and currents from picoamps (pA) to a milliamp (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. A magnetic beam washing option is available which provides significant improvement in beam uniformity. An electrostatic focusing lens provides control of the flood beam spot size, which is typically in the tens of centimeters. However, as a flood-style gun, the spot size is also partially dependent on the grid, anode and working distance.

The gun features an adjustable cathode feedthrough assembly that allows the mechanical alignment of the firing unit with respect to the anode and the column. This alignment can be done in real-time while the gun is operating at full voltage with the beam on. The firing unit cartridge (including the cathode, cathode-mount, and Wehnelt aperture) is user-replaceable without the need to remove the gun from the vacuum chamber. Used firing units may be returned to the factory for rebuild.
