Hot characteristics of corrugated-inner-conductor backward-wave oscillator
Hot dispersion equation is derived and solved of the slow-wave structure(SWS) of the corrugated-inner-conductor backward-wave oscillator(CICBWO),the particle-in-cell(PIC) model is constructed and calculated by PIC code.The results suggest an high frequency microwave is obtained with a frequency of 10 GHz,an average output power of 1.1 GW and a power efficiency of 25% when the acceleration voltage is 0.5 MV,the electronic current 8.5 kA,the corrugated period 4.4 cm,the corrugated magnitude 0.23 cm,the inner radius 2.9 cm and the inner radius of the outside wall 4.4 cm.
