Even though most of us view vacuum tubes as electrical antiques, their basic principle of operation (electrons emitted from a heated cathode) still finds application in cathode ray and X-ray tubes and various RF microwave vacuum tubes, such as triodes, tetrodes, klystrons, magnetrons, and traveling wave tubes.
Thermionic tubes are still used in some applications, such as the magnetron used in microwave ovens, certain high-frequency amplifiers, and amplifiers that audio enthusiasts [ who. ] prefer for their "warmer" tube sound. Not all electronic circuit valves/electron tubes are vacuum tubes.

By J.I. Agnew. Vacuum tubes, also known as thermionic valves, or just valves in the UK, are electronic devices whose operation is based on thermionic emission. This is defined as the emission of electrons from the surface of a solid, in proportion to temperature.
The physics of this process concerns the relationship of the thermal energy of the electron with the work function.

Thermionic Emission l b anode cathode: hot filament, radius a anode cathode 1 4 2 Figure Coaxial cylinders: an inner wire (radius a) and outer cylindrical anode (radius b), form a vacuum tube diode.
The cathode is heated so electron evaporation is possible, and a potential diﬀerence V A attracts electrons from the cathode to the File Size: KB. Electron tube - Electron tube - Common tubes and their applications: Many types of electron tubes are involved in RF electric power generation and amplification.
Another class of electron tubes is employed for rectification and switching (thyratrons and ignitrons). Some vacuum and gas tubes are designed merely to illuminate a target, as in the case of a television tube.
The vacuum tube. The vacuum tube has been called the most important electrical device introduced in the twentieth century.
It has given rise to the field of electronics, making possible radio, long-distance telephone, sound motion pictures, television, radar, electronic computers, etc. The basic working principle of a vacuum tube is a phenomenon called thermionic emission.
It works like this: you heat up a metal, and the thermal energy knocks some electrons loose. InEnglish physicist John Ambrose Fleming took advantage of this effect to create the first vacuum tube device, which he called an oscillation : Michael Alba. We see vacuum tubes used in the broadcast transmitters that radio and TV stations send out their signals with.
We also see vacuum tubes used in radar applications. cathode (a negatively charged electrode that is the source of electrons entering an electrical device). anode (a positively charged electrode by which electrons leave an electrical device).
Hyponyms (each of the following is a kind of "thermionic vacuum tube"): acorn tube (a small vacuum tube; used at high frequencies). diode; rectifying tube; rectifying valve (a thermionic tube. Vacuum tube that emits the free electrons by the application of heat is called thermionic valve or thermionic tube.
A vacuum tube consists of cathode (also called as filament), anode (also called as plate), and electrode (also called as grid). The glass tube contains a wire-mesh anode and multiple cathodes, shaped like numerals or other symbols.
Applying power to one cathode surrounds it with an orange glow tube is filled with a gas at low pressure, usually mostly neon and often a little mercury or argon, in a Penning mixture.
Although it resembles a vacuum tube in appearance, its operation does not. 3.) Brief Timeline: History - Thomas Edison discovered thermionic emission when experimenting with lightbulbs, he found electrons left the carbon filament and were attracted to a metal plate placed in a bulb with a vacuum.
Diode vacuum tube invented by John Ambrose Flemming, based on Edison's discoveries. s - Irving Langmuir develops the first 'high vacuum' tubes. magnetic fields have many applications in electronics. Because a vacuum must be provided in the form of an evacuated enclosure in which the electrons can move without collisions with gas molecules, these devices were called vacuum tubes or electron tubes in the US, and thermionic valves in Britain.
InThomas Edison observed thatFile Size: KB. Electron tube, also called vacuum tube, device usually consisting of a sealed glass or metal-ceramic enclosure that is used in electronic circuitry to control a flow of the common applications of vacuum tubes are amplification of a weak current, rectification of an alternating current (AC) to direct current (DC), generation of oscillating radio-frequency (RF).
Thermionic Emission Makes for the Warmest Sound Posted on Ma Ma by Eric Juang I’ve played in my fair share of rock bands, and constantly heard guitar players tout on and on about their “awesome tube amps, dude” and how “they just sound so much warmer” and “nah, I can’t go out tonight, I spent too much money.

Along the X axis is time, and on the y axis is the count of. The Fleming valve, also called the Fleming oscillation valve, was a thermionic valve or vacuum tube invented in by Englishman John Ambrose Fleming as a detector for early radio receivers used in electromagnetic wireless was the first practical vacuum tube and the first thermionic diode, a vacuum tube whose purpose is to conduct current in one.
Vacuum tubes rely on a process called thermionic emission: Heating the cathode causes it to shed electrons into the surrounding vacuum. The current in.

A vacuum tube voltage regulator for ac power units is described, with two novel features. First, saturation current from the filament of a thermionic tube is used as the control element; and second, a feed‐back stablization system is employed which makes it possible to obtain stable regulated voltage conditions with high sensitivity.
It gives voltage regulation of Cited by: 3. Books: A Abell, G. O., Morrison, D., and S. Wolff. Exploration of the Universe. 6th ed.

Tubes were ubiquitous in the early generations of electronic devices, such as radios, televisions, and early computers such as the Colossus which used tubes, the ENIAC which used nea tubes, and the IBM series.

Vacuum Tube (Thermionic) Diode: The first vacuum diode was developed in the early s at the same time as the first solid-state (semiconductor-based) diode.
While vacuum diodes were commonplace until the middle of the 20th century, they eventually lost market share to semiconductor-based : Jeremy S Cook.
The successor to the vacuum tube, the transistor, invented by Walter Houser Brattain, John Bardeen, and William Shockley inhad none of these drawbacks. After the small, lightweight, low-voltage transistors became commercially available and replaced vacuum tubes in most applications, but with the creation of microscopic vacuum tubes.
Brief History of Electronics and Its Development. Electronics’ actual history began with the invention of vacuum diode by J.A. Fleming, in ; and, after that, a vacuum triode was implemented by Lee De Forest to amplify electrical signals.
This led to the introduction of tetrode and pentode tubes that dominated the world until the World War II. History of theThermionic Tube / Valve / Vacuum Tube – Page 3 via an airtight seal.
On most tubes, the leads, in the form of pins, plug into a tube socket for easy replacement of the tube.
Some tubes had an electrode terminating at a Top Cap. The principal reason for doing this originally was the use of four or five pin tube sockets but thisFile Size: KB.Practical Wireless Application. Radio Hookups Radio Questions and Answers Radio Wrinkles A.B.C.
