The Kimball Physics EMG-4215 Electron Gun, with its matching EGPS-4215 Power Supply, is a multi-purpose modular Electron Gun with applications in many areas. The EMG-4215/ EGPS-4215 is a complete subsystem ready to attach to a user’s vacuum system and turn on. The gun has the capability of producing a collimated, small spot or flood electron beam.

Beam current, beam divergence, and beam energy are all adjustable over wide ranges. The energy can be varied from 1 keV to 30 keV. With the lanthanum hexaboride cathode (LaB6), the beam current is independently adjustable from 1 nA to 5 mA. The gun can deliver spots down to 500 μm. Rastering is also available as an option.

The modular design of the EMG-4215 allows either the firing unit assembly or the lens assembly to be replaced. The firing unit cartridge (including the cathode, cathode-mount, and Wehnelt aperture) is user-replaceable without removing the entire gun from the vacuum chamber. The anode is also replaceable. The cathode to anode spacing is internally adjustable to vary perveance.

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 beam on.
