Electron-Inertia Effects in Thermionic Tubes

Abstract

I WAS extremely interested in the communication by Messrs. Ratcliffe and Kownacki1 on the investigation of electron-inertia effects in thermionic tubes. As these writers state, the difficulty in the experimental determination of inertia effects in ordinary valves is that they occur at such high frequencies that accurate measurement is practically impossible. In order to increase the inter-electrode transit time and so decrease the frequency at which the inertia effects become appreciable, Messrs. Ratcliffe and Kownacki propose using a thermionic tube in which the electrons are replaced by relatively slowly moving ions.
