The analytic expression of high order mode electronic conductance model in double gap coupling multi-beam klystron(MBK) cavity is presented. The oscillations of high order modes were studied by the model and field structures have been simulated with electromagnetic field software ISFEL3D. It is shown that there are self-excitation modes 2.9 GHz and 3.89 GHz in the double gap coupling MBK cavity, which is verified by the three-dimensional PIC simulation. In addition, the corresponding self-excitation modes’ frequencies are also given with the temperature increase of the absorbing cavity and coupling ring by the analysis of experimental results.
