A vacuum tube, an electron tube, valve (British usage) or tube (North America), is a device that controls electric current flow in a high vacuum betweenThis is a list of vacuum tubes or thermionic valves, and low-pressure gas-filled tubes, or discharge tubes. Before the advent of semiconductor devicesA vacuum tube computer, now termed a first-generation computer, is a computer that uses vacuum tubes for logic circuitry. Although superseded by seconda vacuum tube. To release electrons into the tube, they first must be detached from the atoms of the cathode.

Radio-Electronics.com, Adrio Communicationsperfect vacuum, which they sometimes simply call "vacuum" or free space, and use the term partial vacuum to refer to an actual imperfect vacuum as oneIn the early days of electronics, vacuum tube (called valves in British contexts) devices (such as radios) were powered by batteries. Each battery hadA vactrain (or vacuum tube train) is a proposed design for very-high-speed rail transportation. It is a maglev (magnetic levitation) line using partlyAn X-ray tube is a vacuum tube that converts electrical input power into X-rays. The availability of this controllable source of X-rays created the fieldThe cathode-ray tube (CRT) is a vacuum tube containing one or more electron guns, the beams of which are manipulated to display images on a phosphorescent(ideally infinite) resistance in the other. A diode vacuum tube or thermionic diode is a vacuum tube with two electrodes, a heated cathode and a plate,In vacuum tube technology, HT or high tension describes the main power supply to the circuit, which produces the current between anode and cathode. Itused in some early vacuum tube radios because they were more sensitive than the vacuum tube grid-leak detector. During the vacuum tube era, the term "detector"power triode is a radio transmitting vacuum tube which can also be used as an audio amplifier and modulation tube. Typically, the plate is machined fromother vacuum-tube oscillators. Vacuum-tube feedback oscillators became the basis of radio transmission by 1920. However, the triode vacuum tube oscillatorflows through the device. Similarly, in a vacuum tube only one electrode can emit electrons into the evacuated tube due to being heated by a filament, solittle mercury or argon, in a Penning mixture. Although it resembles a vacuum tube in appearance, its operation does not depend on thermionic emission ofA triode is an electronic amplifying vacuum tube (or valve in British English) consisting of three electrodes inside an evacuated glass envelope: a heatedcurvature.
