- madengr 8y agoIf you search for “The Tube Guys”, the front cover of that book shows a 94 GHz, 1 MW tube used for an airborne active denial system. Traveling Wave tubes are still widely used for SATCOM.
- CamperBob2 8y agoOther than ADS systems, and the audio and microwave ovens mentioned in the article: - Huge-ass klystrons used to drive particle accelerators (which themselves can be thought of as the largest vacuum tubes ever made) - High-power transmitting tubes used in radio and TV broadcasting - TWTs are still used for some satellite communication work, both on the ground and onboard the space vehicles - There's still no solid-state substitute for X-ray tubes. Hard to find a semiconductor with a 50,000-volt band gap - Cesium-beam tubes used for timekeeping (as well as masers used for the same purpose, for that matter), although entire atoms are emitted in those sorts of tubes rather than just electrons If you don't count fluorescent lamps as "vacuum tubes," those are about all the remaining applications I can think of.
