MEASUREMENTS ON A BEAM-PLASMA MICROWAVE AMPLIFIER.
Abstract
A beam-plasma microwave amplifier with a beam generated argon plasma is described. In the frequency range 2 - 4 GHz the maximum electronic gain was about 5 dB/cm (beam current 2 mA, beam diameter 3 mm, beam voltage 800 V, argon pressure 0.01 torr, focusing field 740 gauss). It is experimentally demonstrated that nonlinearities may under certain conditions raise the gain slightly above the linear, small-signal level. This effect has been theoretically predicted. Furthermore, the electronic gain has been measured as a function of the beam voltage at different frequencies and focusing fields. (Author)
