Guns (Varian)

We have optical and high-voltage design expertise for you.
We’ve built photoemission guns, but our designs use impregnated cathodes, which use thermionic emission to generate electrons from the heat created by the heater or filament. These electrons are then voltage biased by a grid or electrode and focused into the desired direction or circuit.
Cathodes are provided from one of the two leading cathode manufacturers in the US and can be provided with virtually any of the known impregnation mixes and/or coatings. We also have our own proprietary grid forming and manufacturing process which offers better delivery and control over key features.
