摘      要：正Advances of repetitively operated relativistic backward wave oscillator （BWOs） is *** of operating stability of BWO was obtained based on our earlier BWO operating at 100 Hz repetitive rates through changing the cathode and beam *** oil- immersed graphite cathode and water-cooled beam collector were introduced to increase output stability. Experimental results indicate that BWO’s efficiency is up to the highest 33 % at optimum diode voltage,which is consistent with numerical *** BWO could stably operate at rates of 100 Hz with microwave output power of over 1 GW,and the continuous time was up to 5 seconds.
