Abstract

1407_27Computer simulations of plasma-filled backward wave oscillators reveal that the gain of voluminous beam-plasma cyclotron interactions is significantly larger than that of the conventional backward wave oscillation. This slow plasma cyclotron wave is emitted from plasmas and its gain is substantially enhanced only if it also satisfies the dispersion relation of a ripple wall waveguide which couples the slow wave to fast wave. The observation may be employed to interpret previous experiments which display a strong dependence of output power on the magnetic field and can be utilized to build high gain microwave beam-plasma devices.
