Investigation on Stability of the Beam-wave Interactions for G-band Staggered Double Vane TWT
The development of the high output power and ultra-wide G-band travelling wave tube (TWT) using staggered double vane slow wave structure (SDV-SWS) are investigated thoroughly in this paper. It is found that the stability of the beam wave interaction is crucial with the increase of the periods of TWT to achieve the high power and gain. Thus, two kinds of scheme, which are corresponding to Bragg reflector and two stage SDV-SWS are put forward to suppress the reflection travelling wave interaction with non-working mode oscillating. The 580-590W peak power can be achieved with the 90 periods sheet beam SDV-TWT, which is corresponding the gain of about 40.6dB, the electronic efficiency of 5.5-5.6%, and the bandwidth of 35-70GHz in G-band.
