Slow space charge waves can propagate in a magneto-plasma contained within a waveguide envelope. Preliminary results have already been reported showing that microwave amplification is possible when an electron beam interacts with such a system [1]. In these experiments the plasma was produced by the electron beam itself ionizing a low pressure filling of hydrogen in a waveguide of circular cross section which, when empty, was cut off to the applied signals. The present paper is a brief report of quantitative measurements made on the amplifier and their relation with some new expressions for the performance of the device. A fuller account will be published elsewhere.
