Sentence examples for thermionic tube from inspiring English sources

He is best remembered as the inventor of the two-electrode radio rectifier, which he called the thermionic valve; it is also known as the vacuum diode, kenotron, thermionic tube, and Fleming valve.

His work on demountable, high-power thermionic tubes made it possible to establish radar stations in Great Britain by the time World War II began in 1939.

While working for the Western Electric Company, he developed and designed the manufacturing methods for reliable high-vacuum triodes (thermionic tubes) used to provide the amplification needed for transcontinental telephony (1914) and intercontinental radio telephony (1915).

Klystron, thermionic electron tube that generates or amplifies microwaves by controlling the speed of a stream of electrons.

Oscillator, any of various electronic devices that produce alternating electric current, commonly employing tuned circuits and amplifying components such as thermionic vacuum tubes.

The most widely used mechanism in vacuum tubes is thermionic emission, or electron emission by application of heat.

In such a thermionic filament-based X-ray tube, high temperature operation of the filament is necessary to increase X-ray dose rate, reducing the lifetime of the filament especially in non-high vacuum environment.

Recently, a thermionic filament-based miniature X-ray tube with the diameter of 2.25 mm and the dose rate of a 15 Gy/min (at 1 cm water depth) is commercialized for an X-ray source of electric brachytherapy [13, 14].

Miniature X-ray tubes have been developed mostly using thermionic electron sources [3, 4] or secondary X-ray emission [5].

This paper describes a particular design of a thermionic electron gun employable in Sub-millimetric waves vacuum tubes and for spatial environment applications.

This discovery provided impetus for the development of electron tubes, including an improved X-ray tube by the American engineer William D. Coolidge and Fleming's thermionic valve (a two-electrode vacuum tube) for use in radio receivers.
