Actually three special purpose vacuum tubes were specifically designed for microwave usage and are in some cases still the least expensive way to work with high power microwave signals.
These vacuum tubes are:
- cavity magnetron (first designed in WW2 for use in military RADARs, still used in some RADAR systems and as the microwave radiation source in all microwave cookers)
- klystron (still used in satellite communication, medical microwave equipment, and particle accelerators)
- traveling wave tube (still used in satellite communication, RADAR systems, and the electromagnetic compatibility (EMC) testing industry for immunity testing of electronic devices)

What are the applications of neon?
Some of it's uses are Vacuum tubes, high-voltage indicators, lightning arrestors, wave meter tubes, television tubes, and helium non-lasers.
What is the common uses for neon?
Neon is used in lighting, most commonly known for its use in neon signs. It is also used in vacuum tubes, high-voltage indicators, television tubes, and helium-neon lasers.
What are the two most recognizable types of electron tubes?
The two most recognizable types of electron tubes were the ordinary television and computer tube and the once common vacuum tube traditionally used in radios and other electronic equipment.
What is the helix of a wire?
A helix is a 'loose spiral' rather than a tightly wound spiral. Often used in vacuum tubes to amplify an electron beam.
How does Multi-effect Distillation work?
It is a process of distillation of sea water to get almost pure water. It has many stages. In first stage steam is introduced in the tubes and sea water sprayed. Stage is slight under vacuum so the flashing occurs and vapour produced which will condense in next stage in the tubes and so on.
How many vacuum tubes are in the Univac I computer?
It used 5200 vacuum tubes.
What are the microwave tubes is based on the principal of velocity modulation?
the microwave tubes that undergoes velocity modulation are klystron tubes ie, two cavity klystron.....
Do all vacuum tubes light up?
No, there are some cold cathode vacuum tubes. These do not light.
What has the author A S Gilmour written?

Where is a good place near Seattle where you can buy old vacuum tubes?
This would depend on the type of vacuum tubes needed. Any car part store will carry vacuum tubes for a car, general stores carry vacuum tubes for household vacuums, and AC part stores will carry vacuum tubes for the AC/Heating system of a house.?æ
Where was vacuum tube was made?
who made the vacuum tubes
How many vacuum tubes in first generation computer?
ENIAC was the first digital general purpose computer, built in 1946, and with 17,468 vacuum tubes. The Illiac I, the first computer built and owned by a US educational institution, had 2800 vacuum tubes. The IBM 604 had about 2000 vacuum tubes.
What technology replaced vacuum tubes in the second generation?
Vacuum tubes were first replaced by transistors, and later by integrated circuits.
Why modern devices use integrated circuit instead of vacuum tubes?
Modern devices use integrated circuits instead of vacuum tubes because integrated circuits occupy less space than vacuum tubes, are more efficient, consumes less energy and are more reliable than vacuum tubes.
Vacuum tubes generation?
first

Which is better a vacuum tube or a micro chip?
It depends on the application. Vacuum tubes work better under certain operating conditions and frequencies. The problem with vacuum tubes is they are not as easy to mass produce as semiconductor devices, and semiconductor devices such as integrated circuits can have litterally thousands or millions of transistors and other components on a single chip. Such scaling is not possible with vacuum tubes, though there is some research in the MEMS (Micro Electro Mechanical) field to suggest that micro scale vacuum tubes could be mass produced within an integrated circuit. Such applications could be useful in the Terahertz frequencies. When a lowcost and compact solution is preferred generally the silicon based microchips will be the best option.
