 (ĭg-nī′trŏn′, ĭg′nĭ-)
A single-anode, mercury-vapor rectifier in which current passes as an arc between the anode and a mercury-pool cathode, used in power rectification.


(ɪɡˈnaɪtrɒn; ˈɪɡnɪˌtrɒn)
(Electronics) a mercury-arc rectifier controlled by a subsidiary electrode, the igniter, partially immersed in a mercury cathode. A current passed between igniter and cathode forms a hot spot sufficient to strike an arc between cathode and anode
[C20: from igniter + electron]


(ɪgˈnaɪ trɒn, ˈɪg nɪ trɒn)

a rectifying vacuum tube with an auxiliary electrode projecting into a pool of mercury that conducts current when the anode is positive.
[1930–35; igni (te) + -tron]
