Abstract：
To design the coupler of one kind of thermionic cathode microwave electronic gun, we apply the ``energy method'',which calculates the coupler factor between the waveguide and cavities of the electronic gun. So we can design the geometry size of the coupling iris. MAFIA code is used. Comparing with the experiment results,the simulating results is in agreement with measurement about 10%—30% deviation. ``Energy method'' is an efficient and simply method to calculate the coupler factor between cavities and waveguide.
