Abstract A linear and nonlinear analysis of a crossed field gyrotron operating on theTEm11 whispering gallery mode are presented. The detailed discussions are given for the starting oscillation condition, the effect of the internal conductor in coaxial cavity on the cut-off frequency of mode and spacing between adjacent modes as well as the effects of the applied voltage on the cyclotron frequency of electron, the starting oscillation beam power and electron efficiency. It is shown that the efficiency of 41% may be obtained for m=2. A comparison of these results with those in cylindrical cavity is made. The analysis is helpful for the engineering design.
