Abstract
A cooling system for a screen grid electron tube such as a high power, high frequency transmitter tetrode which has coaxial formed electrodes and bushings and has an air cool screen grid terminal formed of two angular screen grid terminal elements 1 and 2 spaced from each other in the axial direction together with their bushings 3 and 4 so as to form a cooling air coaxial passage 7 so as to cool the screen grid terminal elements 1 and 2.
Claims4
Apparatus for cooling a screen-grid electron tube having an envelope such as a transmitter tetrode which operates at high power and at high frequencies and which is mounted in a tube holder, said tube having two annular screen-grid terminal elements (1, 2) which are coaxially arranged and are axially spaced from one another, said tube holder having two annular coaxially arranged and axially spaced bushings into which said two annular screen-grid terminal elements (1,2) are mounted and said two bushings (3, 4), forming coaxial cooling air passages (7) between said bushings and said screen-grid terminal elements (1, 2).
