It is shown that plasma leads to increased Q values of cavity models. Also it results in a downshift of the operating frequency and an increase of the RF field inside the gyroton cavity. Estimates of these effects in a wide range of plasma densities for the l MW 140 GHz CW gyotron at FZK are presented. The investigations are based on the plasma one-fluid model assumption.enTechnikConference Paper10.1109/MMET.2004.1396985Conference Paper
