| Abstract: | A presence of a controlled amount of background plasma inside relativistic backward waveoscillator (RBWO) can lead to improvement in its characteristics beyond what is available in evacuateddevice. Recent results clearly demonstrated the presence of plasma can significantly increase the efficiencyand power handling capability of RBWO,and allow operating without a guiding magnetic field, and haveWider tunibility by controlling the density of background plasma.The recent scientific advances in this fieldboth theoretical and experimental all over the world are systemically reviewed and some suggestion todevelop plasma-filled RBWO are presented in the paper. |
