phanotron Electronics.|ˈfænətrɒn|
Also phanatron.
[f. phano- (? f. Gr. ϕαίνειν to bring to light, cause to appear) + -tron.]
A thermionic diode rectifier utilizing an arc discharge in mercury vapour or gas at very low pressure.
Formerly a proprietary name in the U.S.

Morecroft Electron Tubes viii. 193 In the Phanotron a low temperature filament must be used, because the mercury vapor has not enough density to prevent the evaporation of the filament. 1939H. J. Reich Theory & Applications Electron Tubes xii. 430 The construction of the type FG-166 phanatron. 1966McGraw-Hill Encycl. Sci. & Technol. VI. 62/1 Typical phanotrons have average current ratings from 1·25–10 amperes and peak inverse voltage ratings of 10,000–22,000 volts. 1975Yeager & Gourley Introd. Electron & Electromech. Devices (1976) xiv. 283 We will discuss two types of gaseous discharge: arc discharge and glow discharge... Arc discharge tubes are commonly called thermionic gas tubes; for example the gas diode (phanotron) and the gas triode (thyratron). |
