Electron tube having linear damper

DETAILED DESCRIPTION It is, therefore, an object of the present invention to provide an electron tube capable of reducing a space for fixing one or more pairs of auxiliary linear members, the number of process and member therefor, and the number of wiring thereof and terminal for extracting the wirings to an outside by fixing one or more pairs of auxiliary linear members to a common fixing member or separated fixing members formed on a same substrate.
In accordance with the present invention, there is provided an electron tube comprising: a vessel; a primary linear member installed in the vessel; an electrode disposed in the vessel; a first auxiliary linear member and a second auxiliary linear member disposed at different heights to interpose the primary linear member therebetween; and a plurality of fixing members, formed at a single substrate for constituting a part of the vessel, for fixing end portions of the first auxiliary and the second auxiliary linear member thereto.
