High-voltage and optical design expertise

We supply both custom and production Electron Guns and Electron Sources for OEM’s and various research entities. Our Electron Guns and Electron Sources are used on Traveling Wave Tubes (TWT’s), Klystrons, X-ray Sources and primarily on linear accelerators for medical (oncology), industrial screening and national laboratory applications.

Electron guns are assembled by highly trained and skilled technicians who also have prior electron gun building ex perience. Absolute cleanliness and attention to detail is used to make all our electron guns. Several high magnification optical inspections and measurements are recorded during the build. Most electron guns are baked-out and stored in vacuum-tight metal canisters while some are also hi-potted (high-voltage processed and conditioned) and emission tested, where cathode roll-off curves are inspected for conformance.
