Abstract

The first conclusive experiments demonstrating microwave amplification when an electron beam is passed through a plasma were carried out in 1957 by Boyd, Gould and Field [1]. These authors demonstrated that there is gain below the plasma frequency, reaching a maximum at the plasma frequency. The theory they used predicted extremely high values of gain, much higher than were observed experimentally, the maximum value of gain being limited only by thermal effects and collisions of the electrons with neutrals and ions.
