ELECTRON BEAM-PLASMA INTERACTION: THE PLASMA MAGNETRON.
Abstract
A low-power plasma-loaded smooth-bore magnetron is investigated experimentally. Two experimental versions are described. The first, operating under a bell-jar with a 500 gauss permanent magnet, exhibited oscillations in the range 300-500 mHz and 2-3 gHz. The second, a demountable structure operating in a variable magnetic field, exhibited oscillations in the range 970-1000 mHz. A theoretical model is discussed which postulates the interaction of the negative space-charge wave of a rotating cloud of primary electrons with the azimuthally traveling waves associated with the quasi-static modes of the plasma. The plausibility of this model is discussed but an experimental verification of its applicability was not achieved. (Author)
