Vacuum Tube Design

Vacuum tube is the old term for an electron tube or a vacuum electron device. It covers a broad range of devices which have vacuum envelopes and free electrons moving inside them. We specialize in designing and making the following vacuum tubes: streak tubes; cathode ray tubes; low frequency amplifier tubes (triodes, pentodes and tetrodes), X-ray tubes and microwave tubes. Our favorite microwave tubes are traveling wave tubes and klystrons. We are actively engaged in research on lightweight, electrostatically focused klystrons and traveling wave tubes for space applications.

We also rebuild tubes if it is economically feasible. For example, an out-of-date cathode ray tube can often be reconditioned by merely changing its cathode and sometimes resettling its phosphor screen.

We also build testers. These are special purpose tubes for testing devices, materials or components. They may be used for testing cathodes, electron guns, electron bombarded semiconductors, X-ray targets, phosphors, or the vacuum properties of glues or other organics. Because we use glass, we can build these devices quickly and inexpensively.

Vacuum tube design and construction is our specialty. For more information on how we may assist you in your vacuum tube design needs, please reach us through our Contact Us page.
